Generally the only reason to be on
Viagra is if you are on the older side in years
and have had some of these problems
and they can't be fixed. But older folks usually are more concerned with sex with a partner, so I'm just wondering, do you have sex with others, how old are you, and how did you get a prescription for Viagra if you're a young guy who mostly masturbates at this point in your life. The main cause of ED are mental issues.
