What about the long term psychological effects of taking stimulus like this?
A friend of mine in his 30's always takes either Viagra or an alternative before sex, I imagine in tiny doses. In my eyes it wouldn't be too difficult to go from taking it to enhance a sexual encounter as a one off novel experience to using it to get the most out of casual sex and then being too afraid to not use it because you're worried you won't be able to maintain an erection or get any pleasure out of sexual stimulation.
To me the whole thing seemed rigged to pull on your insecurities from the get go. Sure it helps with ED, I'm not denying that. I guess I'm pro gaining sexual experience and learning more about various sexual techniques the old fashioned way. Like the musician, Sting.
I'm Sting.
