For Erectile Dysfunction "Commenting as my husband’s wife. He is 38 and started dealing with unreliable erections. He went to his doctor and got 100 mg of sildenafil. He’s had the prescription for about a year, but doesn’t need it all the time. He only took 25 mg the first time and wow was he rock hard. He took it about an hour before we hooked up, but was ready to go within 15 mins just by looking at me. I was so turned on by his ability to stay hard and get me off back to back to back. We had hot passionate hardcore sex for hours and then the following morning too. I couldn’t get enough of him! This pill gave him his confidence back and he no longer stresses about sex. He still uses the pill occasionally, maybe once every couple of weeks. I get so excited when he pops a pill because I know how incredible our night/morning will be. 100% recommend from a woman’s perspective!"

Sildenafil for Erectile Dysfunction "I don't know why people continue to try various chemical-based meds like Viagra and others when herbal medicines offer an effective, natural, and permanent treatment for erectile dysfunction. I am 58 years old, and I can attest that in all my life, only herbs have helped make my penis grow longer in length and bigger in girth, as well as helped me get rid of ED and premature ejaculation. Even at 58 years old, I'm still very strong and sexually active like a 20-year-old man. All thanks to natural herbs from my personal herbal doctor (Dr. Guru). Since the last 9 years, my whole sexual health has become really great. Thank you for helping me get rid of erectile dysfunction, and thank you for your herbs that helped me gain extra length on my penis. Dr. Guru, I must admit, you are an excellent doctor. Well, anyone here who needs help curing ED and getting real penis enlargement herbs should go to Doctor Guru on email: dr.guruherbs@gmail.com or you can text, call, or WhatsApp him directly."

Sildenafil for Erectile Dysfunction "I am 68 and had begun to have inconsistent erections or would lose it during intercourse. My wife and I decided to bring it up with my doctor who prescribed Viagra. It has worked very well. I take it an hour after dinner. Within an hour I am ready to go with rock-hard erections. I am also able to last longer. My wife has loved it. Perhaps the best sex of our lives, even after having 5 children! Side effects have been minimal and seem to be subsiding from a little flushing, stuffy nose, and slight headache."

Sildenafil for Erectile Dysfunction "Had a normal sex life with my wife of over 35 years. I’m 64, my wife is 59. Started to have a hit-and-miss issue with achieving an erection, although we both had the normal foreplay. Spoke to my doctor, and she advised I try Viagra Connect after carrying out blood tests. The experience I achieved after taking my first dose was totally worth the cost of purchasing. It has re-energized our sex and love life."

For Erectile Dysfunction "This is a good medication that is mild with side effects. Just a bit of a flush feeling to the face once in a while, slight headache. Overall, I need 25 mg, and I’m hard enough for sex. Thanks for having integrity and ethics to make it safe for everyone but effective."

For Erectile Dysfunction "At 70 years old, my GP prescribed Viagra due to ED issues. These ED issues have come about as a result of cardiovascular disease and age. The taking of blood pressure medication didn’t help. Up until then, I had no erectile issues. I now take a 20 mg tablet cut four ways to effectively equate to 5 mg. I always take the Viagra on an empty stomach and find it effective within 20 minutes and probably stays in the system for four or five hours, during which time I can easily obtain another erection. It’s made a huge difference to our relationship, whereas in the past, keeping an erection for penetration became a rarity and very frustrating for us both. The only two side effects that are noticeable with such a low dose are an upset stomach, which I put up with given the benefits, and that sometimes orgasm for me doesn’t happen. Prior to Viagra, orgasm was never an issue. I hope you find this review helpful."

For Erectile Dysfunction "I've been taking sildenafil for over 5 years and am now 82. Have been on 50 mg for a while, taken 1 to 2 hours before sex. Absolute magic, getting really hard soon after arousal and not having to worry about losing it for an hour or more. Goes flaccid soon after ejaculation, but it would get too tender if it was used much longer! Wake up the next morning with an incredible erection which can be put to use again if required."

For Erectile Dysfunction "I'm a 59-year-old stage 2 prostate cancer survivor who finished my cancer treatment regimen in March 2023. Beginning January 2021, I was on leuprolide shots every 4 months and daily abiraterone with prednisone chaser, so my testosterone was completely shut off, including losing all interest in sex. Four months ago, I finally started noticing a small return of my libido, but my free testosterone levels are still far below the standard range. Two months ago, I began a new relationship with a woman: our first sexual contact was extremely nice, but I was unable to stay hard. She gently suggested looking into Viagra, which I happily did. My urologist agreed and prescribed 40 mg (two 20 mg pills) as needed. I 'test-drove' it at 20 mg, with marginal results. I tried the full dose 2 days ago on an empty stomach, and it worked like crazy! We both were very happy. A tiny bit of dizziness and a small headache the next day, but breakfast took care of that. If you need the boost, I recommend it 100%."

For Erectile Dysfunction "I am 37, and my wife and I have been married for 15 years this year and dated for 2 years prior to that. She is incredible and even more attractive to me now than when we met. A couple of weeks ago, I noticed I was going soft during sex, and it then went from bad to worse over the next subsequent sessions. She was very patient, and I told her it was me, not her. I went to the doctor, and he gave me a prescription of sildenafil 100 mg tablets to get my “confidence back”. I used a dose of 50 mg and after taking it an hour and a half after eating dinner, I was hard within 5 minutes just by the sight of her. I felt hard and fuller for the 2.5 hours we stayed up. I didn’t have to worry about my erection being lost. I did feel it harder to ejaculate after the first time, and I was able to have sex again in the morning and later the next day without another dose. My sex life went from a 10 to 15 overnight. The only side effect was a slight headache, but nothing painful which would require pain medication."

For Erectile Dysfunction "At 64, I had not lost the ability to get an erection but could not always maintain it during sex, or get hard enough for some positions. I got a script for generic 50mg. I tried it twice, split to 25mg. I wanted to test for side effects. The 25mg helped me get a little harder but helped more with recovery time (I was able to go again almost immediately). The 50mg though was like being young again, full upright erection and able to keep hard right through an orgasm, and as much as I wanted and from every position. I’m convinced! Slight side effect of facial flushing at 50mg but not a lot. Also had a headache later (about an hour or two after half-life)."

Sildenafil for Erectile Dysfunction "I'm in my early 50s and have found it difficult lately to achieve an erection. So, I started on sildenafil 25mg but this didn't work for me, so I increased the dosage to 100 mg. I found it best to take a couple of hours before going to bed. After some foreplay, I was rock hard and my wife and I had hard, vigorous sex for over an hour. I had an explosive orgasm and I was able to carry on until she came. My penis was bigger and thicker than normal, and after 20 minutes, I was rock hard again, and we had sex again. I found it difficult to reach orgasm the second time, but my wife wasn't bothered as she came twice. We went at it for ages, was hard all morning, and we had sex on and off. The only side effect I experienced was a slight headache, but I just took some paracetamol. This medication has really boosted my confidence, and my wife is delighted. I have also cut the tablet in half lately, and this is satisfactory. Oh, and take it on a completely empty stomach for best results."

For Erectile Dysfunction "When I reached 50, I noticed my erections were not as strong, or not at all. I done some digging online and decided to try sildenafil. I purchased some at 25 mg. After some foreplay, I was fully erect and my wife and I had sex, but I soon lost my erection. So I thought I should just buy the 100 mg tablets. On reading reviews, it advised to take on an empty stomach, so I did and an hour before sex. We had foreplay, but nothing happened, thought it hadn't worked, but after approx half hour more (1 half hours) - wow! I hadn't been that hard since I was 16, my penis was bigger and thicker. We had really good sex. I lasted way longer than normal. I had an amazing climax and was able to carry on until my wife climaxed. I was rigid again in around 45 mins, and we had sex again. I found it hard to reach orgasm the second time around. In the morning, we had really good sex again. I have since reduced dosage to 50 mg as I thought 100 mg was maybe too much. Only side effect was fatigue, but well worth it."

For Erectile Dysfunction "I got to 50 and was struggling to maintain an erection. So, I bought sildenafil 25mg but these didn't do anything for me, so I increased the dosage to 100mg. And it worked very well. I find it best if I take it on an empty stomach and about 2 hours before having sex. I also found it increased the size of my penis, and I also lasted longer. After my wife and I had finished, my penis was flaccid for around an hour, and then it was fully erect again so we had sex again. I had not done this for many years. And again, we had sex in the morning. I would highly recommend this treatment, it has done wonders for our sex life. The only slight side effect for me was a little heartburn, but the positives far outweigh the negatives. I would highly recommend."

For Erectile Dysfunction "The struggle, the head aspect of intimacy. I have suffered sexual abuse, developed anxiety disorders, low self-esteem, and stress from life. These factors affect me not just mentally but physically, making it hard to enjoy intimate moments. Since taking this, I can focus on the moment and enjoy it. I feel more confident. This lowers my stress, anxiety, and raises my self-esteem. I have taken various dosages. If you're like me, under 40, you probably don't need the 100. I've tried it and I've been told it can be too hard from my partners. I like the lower ones because I can sort of feel it working but still get hard when I want. I have noticed some heartburn, usually after the dosage is done."

For Erectile Dysfunction "Has anyone noticed that they do not have to get up to urinate as often after taking sildenafil? For me, it is a very positive side effect, but my doctor thinks I am making it up. Instead of having to get up every 1-2 hours, I can sleep soundly for five or more hours, which makes it worth it. Are there any downsides to this side effect?"

For Erectile Dysfunction "I'm not an old guy, but I have a back injury which makes my landing gear hit or miss. I really didn't worry about this because I work full time. Well, an old hag at work had been coming on to me, and she's a lot older, so I was like 'hell no!'. Long story short, after a year of hiding from her, we were both at a cookout and I was not feeling well. She offered me a ride and ended up taking me and dumping me on her couch to recover. She said she was worried about me. A while later, she was all over me and stuff wasn't working though. She went and found me a 100mg pill, and I took it. Shortly after, we had phenomenal sex! An old hag too! I mean, we went 3 times in about 7 hours. By far the best sex I ever had. I have been knocking the bottom out of her ever since. So glad for sildenafil! She could look a bit better, but the sex is out of this world so I don't care. We have been at it for about 8 months now."

Sildenafil for Erectile Dysfunction "In my early 60s, I have what I'd describe as moderate ED: getting and staying hard has become more difficult. Spoke to the doctor who prescribed Viagra. I tried one 50mg tablet to see if it works. After about 45 minutes, I was able to get aroused and had a hard-on like never before, fully erect, upright, thick, and very stiff. I'd say slightly reduced sensitivity. Came like the old days solo. Can't wait to try it with my wife. Bit of a headache during and afterwards but worth it."

For Erectile Dysfunction "After nearly 40 years of marriage, I suddenly found that I wasn't staying hard enough to have full penetrative sex. I first thought it was a one-off, but after it happening 6 times in 2 weeks, I went to see my doctor. He asked lots of questions and decided that I was ideal for sildenafil, and he prescribed me 50 mg. After reading all the instructions, we gave it a go. The first time was on an empty stomach, as it said this was best, and we waited an hour before getting down to having some fun. My god, it was so good to feel like a man again and get an erection that fulfilled its job. We were very happy. 2 days later, we had been out for a meal and felt that we wanted to try the tablet again. I waited for 2 hours before taking it, and then another hour before we tried. Once again, a cock so hard I could have punched a hole in the wall. After about 45 minutes of play, my wife got on top and rode me like a stallion. The orgasm I get is amazing. We went 3 more times that night, not something we've done for a few years. Thanks, sildenafil."
