Viagra (sildenafil) for Erectile Dysfunction: “I am 66 and have been taking Viagra for about 5 years. My wife and I had a great sex life that just seemed to hit a brick wall about five years ago. She didn’t complain but one day we were trying to remember the last time we had sex. During my next doctor appointment I discussed this with my doctor and he had some bloodwork done. A few days later I got a call and my T levels were extremely low and I was referred to a urologist. He asked me a very simple question, if I still got morning erections. I had to think about that for a moment and the answer was no. Once the bloodwork results proved very low he prescribed Viagra. The results were immediate but it took me a few months of experimenting to determine when and how to take it. My erections are back. My wife will take a pill out of the bottle and put it in a special place to let me know she’s in the mood or if it is a date night. Learn to use it and how it works best for you and your significant other.”

Viagra (sildenafil) for Erectile Dysfunction: “Sildenafil works for me as directed, it will definitely work better between meals as any drug will. My problem is I feel like garbage for the next day sometimes the next day after that. Generally feel like a cotton head foggy brain just kinda out of it. I have tried Cialis with the same result. Does anyone use anything else that might flush out of your body faster. There is a supplement called L- Argenine that I feel like it might work when I take it ( like I might get hard) but haven’t put it to the test. Anybody have any experience with anything else?”

Viagra (sildenafil) for Erectile Dysfunction: “I love this stuff! I get a little face flushing, stuffed up nose, and itchy eyes but damn, it's all worth it. I had given up on ever getting fully hard in my early 50's but this stuff makes me feel like a teenager again. Took a 100 mg pill for the first time last night (I had been cutting them in half) and had great sex within an hour. Woke up with my best erection in years in the middle of the night. Damn near woke the wife up! She was mad that I didn't! Well, round 2 tonight then!!! It's generic now so just get some and then go get some!!!”

Viagra (sildenafil) for Erectile Dysfunction: “I'm 51 & healthy. My erections were semi-hard and took a lot of stimulation. Was able to penetrate but would loose erection if wife got on top. Doctor prescribed 60 mg generic Sildenafil (20 mg pills) I took 60 mg 1 hour before. Was able to get rock hard as soon as wife touched it. Had sex for 30 min and she was on top until she climaxed. No problems. After ejaculation I waited 10 minutes and was able to get rock hard again, had sex for 30 min but found it difficult to ejaculate. Side effects: feeling hot & flushed. Tried 40 mg and was able to get fully hard but it took a little more stimulation. When wife was on top I it wasn't as hard so we switched positions. Ejaculated after 30 minutes & had to wait an hour to get hard again before another 20 min of sex. No side effects with 40 mg. I will cut one of the pills in half to see if 50 mg is sweet spot between potency and side effects. Wife is happy. I hadn't been able to have sex twice in the same hour since we were in our twenties.”

Viagra (sildenafil) for Erectile Dysfunction: “I have been taking Viagra for about 15 years. It works great for me with minimal side effects. One 50 mg tablet turns me into a raging bull for about 18 hours. The key is to always take it on an empty stomach. I discovered that if my body is low in salt, the Viagra does not work as well. I exercise daily and sweat heavily, which depletes salt from the body, so I make sure to add some extra salt to my diet.”

Viagra (sildenafil) for Erectile Dysfunction: “My confidence has been diminishing over the last few years, and by age 45, I noticed that my erections were not nearly as firm as they used to be, so I had an on-line consult with a Dr., who presecribed Viagra. 50mg to start to a max of 100mg. I did notice improvement taking 50mg, I had a confident erection that I didn't lose when it came time to put on a condom. Recovery time was better, but overall I wondered if it could improve. I moved up to 100mg, and WOW, what a difference! I am ready to go, any time. Barely any recovery time, and my partner and I had a number of sessions over a span of 4 hours, and I could have kept going. Even into the next day, strong erections were easy. I took the pill on an empty stomach, an hour before the fun started. I did notice that while I did keep erect longer and more often, ejaculating was more difficult after the first time. My partner didnt mind though! Really happy overall. No side effects.”

Viagra (sildenafil) for Erectile Dysfunction: “Suffer from erectile dysfunction due to coronary artery disease and take a beta blocker. Finally asked my doctor about pills and he gave me a sample pack 50mg of Viagra. Doc said I was a definite candidate for Viagra. I first tried the 50mg with success. About 10 days later I cut one in half for a 25mg. The 25mg was more than enough. Very minimal side effect only for a few minutes when first taken. No real problems. Have not had erections like this in many years. A great pill for all guys with erection trouble.”

Viagra (sildenafil) for Erectile Dysfunction: “My husband is 16 years older than me and was diagnosed with diabetes and ED. Active 46 yr old at a healthy weight. 6' tall and about 180 lbs. He use to take OTC herbal supplements which worked with with unreliable success but he finally talked to the dr and was given viagra samples.He takes 50 mg at a time. The viagra is much more reliable. He takes it right before foreplay and is rock hard right on cue 30 to 60 minutes later. Slight headaches sometimes but never enough to curb his appetite. Now his performance matches his desire and we both have multiple orgasms. It definately works best on an empty stomach or eat low fat foods.”

For Erectile Dysfunction: “I have had heart problems and HBP for years but recently had erection probs. The doc put me on sildenafil I started with 40mg dose and it worked but not as well as I wanted so the doc upped the dose to 100 mgs. It gets me a usable erection but I would call it firm but not hard and I always feel that I am about to lose it. Any ideas on how to make it hard instead of just firm?”

Viagra (sildenafil) for Erectile Dysfunction: “I'm 43 and recently widowed. My wife was an alcoholic and it was a turn off for sex. For years, I kept telling myself I won't let her get me excited. I started realizing that I wasn't able to gain a full erection and thought it was due to high blood pressure. That, or I psychologically made myself erectile dysfunction. A while after she passed, I met someone amazing, but my performance was less than amazing and I feared I would lose her. I asked my doctor if there was something I could do. He prescribed Viagra at 50mg. After reading what everyone posted here, I cut one in half, but, once it took affect, it was JUST better than without. I took the rest and was rock hard. I even had a couple beers after to celebrate. Woke up hard as well. No side effects.”

Viagra (sildenafil) for Erectile Dysfunction: “I was finding it more and more difficult to get an erection and when I did get one it was not as hard as it was a few years ago. I also found that I could not maintain my erection as consequently sex was being rushed so much so my wife was left unsatisfied. My doctor prescribed 50 mg Viagra which helped but did not completely solve the problem. She then upped my prescription to 100mg and this had been amazing. After about 45 minutes of taking the Viagra just the thought of sex gives me an erection whereas previously my wife had to give me a lot of stimulation to get me up. Also my erection is a lot harder and is maintained as long as we want. It really is fantastic.”

Viagra (sildenafil) for Erectile Dysfunction: “Age 75 and had problems with having an erection for about two years . Had good sex with wife but it was a poor substitute for sex we had even five years ago when erections were hard and long lasting. Just bought Viagra 50 mg with marvellous results. After 45 minutes erection as hard as 50 years ago and great climax in vagina. Two hours later a similar result and even woke next morning with a very pleasant erection. Can’t wait for next sex session.”

Viagra (sildenafil) for Erectile Dysfunction: “I'm a 29 year old male. I have been using Viagra for a while to treat erectile dysfunction. I use the 50mg pills. I find Viagra to be extremely effective. The only side effect for me is a mild hot flush after taking one which I actually find to be mildly pleasant. It's usually the first sign that the drug is taking effect. I get a very strong and long-lasting erection from it. I also find that I last longer before ejaculation and it gives me a shorter refractory period. It has been a miracle drug for me. I would highly recommend getting Viagra instead of generic sildenafil if you can get it for a similar price.”

Viagra (sildenafil) for Erectile Dysfunction: “I am 77 and have been taking Viagra for 6 months. A really wonderful medication ! Was having unreliable and short duration erections. I started with 50mg but reduced to 25mg and kept the great results. Hard for approximately 30 minutes a session always ending in sensational climaxes. Have increased frequency of intercourse to about 5 day intervals (34 times over the past 6 months !). This is because the sex is so fabulous and we are both not at all impatient to finish. No side effects. Recommend it for all you older guys, but you should also keep physically fit.”

Viagra (sildenafil) for Erectile Dysfunction: “I'm 49 with no major Erectile Dysfunction, but occasionally can't get an erection. Typically performance anxiety. I got Viagra for occasional use. I got a special pill cutter to cut my 50mg in half. I took it when we went out for dinner (1 drink only) and when we got home (on hour later) we began to play around then the "magnificent" appeared; 20 minutes and several orgasms later we were spent. Viagra will turn you a stud. I highly discourage it for regular use, maybe once a month and only 25mg if you don't have erectile dysfunction. ”

Viagra (sildenafil) for Erectile Dysfunction: “After being a quadriplegic for 20 years, I found myself in a situation where sex was involved. Though I could get an erection, it was not fully hard an only lasted around 5-10 mins. One 100mg tab and to my surprise after only about 20 mins I felt myself stirring, though they say viagra doesn’t cause erections, in my case it did. My penis stiffened to a hardness not felt since before my accident and stayed that way for almost 3 hours. Amazing, I thought as this was only a trial run and I had no one to share my good fortune. The effects were still felt for about 48 hours with my “normal” erection being harder and longer lasting and, I swear my erection is bigger in thickness and length. Probably from being fully erect after so many years.I am thoroughly pleased with the results, far beyond my expectations. I’m very happy.”

Took about an hour to kick in but then lovely firm erections for a number of hours. Managed a number of ejaculations which was another bonus. Side effects were dizzy spell, very mild headache. ”

Happy wife September 11, 2015

Viagra (sildenafil) for Erectile Dysfunction: “I don't see any women commenting, maybe I'm the first? My husband is 13 years older than me, started having "unreliable" erections a few years ago (in his late 50's) This was causing me to feel insecure, thinking maybe he just wasn't turned on by me anymore. We did not discuss it, I was afraid it would cause anxiety and make matters worse. Viagra was recommended by a friend, so we tried it and that was the best erection my husband has ever had! (In 25 years!) I tell him it just helps him meet his best potential. So this has been a part of our lives ever since. The 45 minute wait is actually kind of a turn on because I know what's coming. I love it and I highly recommend. Side effects: blurry vision and stuffy nose.”

Viagra (sildenafil) for Erectile Dysfunction: “I am 73. Been taking Viagra for some years with mixed results. Have a meal about 6pm and take Viagra around 8pm. At 11pm not a great erection and won't last, but at 7am next morning a great and lasting erection. My wife does not prefer morning sex but will to please me. I prefer late evening sex after a bath/shower I think the meal gap not enough? Viagra seems to get absorbed overnight and hence good hard in the morning. Effect last a lot longer than the 4 hours suggested. Maybe I'll try taking it earlier”

Viagra (sildenafil) for Erectile Dysfunction: “After years of ED I was finally prescribed Viagra. 50mg was only partially effective so I went onto the 100mg tablets. The effect was amazing, 1 hour after taking the 1st tablet I had the hardest erection I'd had in years and the stamina I had was as though I had gone back to my 20's and 30's. My wife was highly impressed with my performance especially when we had sex for 3 nights in a row and now walks around with a smile on her face again, as do I!”
