What is the most powerful sexual drug for erections?

one of the most common is the one that you listed viagra if you continue to have this problem and this medication is not effective then I think if it were me then I would discuss this with you medical doctor or Urologist, I really believe that suggesting something other than what the doctor has you may have other problems along with this or you may be on a medication that renders this ineffective, bottom line I just want the very best for you, giving you the wrong advice is the last thing either I or anyone else on here would want to do please take good care and be safe

The treatment and what's best for your erectile dysfunction depends on the cause of problem. Please discuss other options with your doctor.
