Any longterm concerns on Viagra?
I bought generic viagra, and I have just used it once with masturbation to see whether it is working or not. This weekend I may use it with my girlfriend. However I was talking with a friend, and he has sort of made me concerned regarding the use of Viagra. If my dick gets used to staying up due to Viagra, then once I can not find Viagra one day what would be the functionality of my dick? Would it lose its capability to get erect?
Did anybody among you take Viagra for some certain period of time, then stopped taking it then observed some negative side effects this way?
By the way I am just going to take 25mg for recreational purposes. I mean to be able to have longer sex.
