Hi, I am 32 years old, I ve always had problem with erections and I never come during sex unless I masturbate. I never have sex unless I use Viagra I ve been having like a nervous tick and It makes me either contract my penis or sort of press it with my fingers through my pants. I feel like by doing this, made my penis even shrink. I am so worried about the situation that I think about it all the time. I ve been reading so many articles and methods, I dont know what else to do, I feel It s time to give up on everything. Would appreciate your advice
