Last year I was taking SSRI's on the advice of my doctor. One of the side-effects that I felt too embarrassed to talk about was that it shot my sex-drive thru the roof. For a few months I was masturbating a lot and trying to have sex as much as possible. The thing I'm getting at is that was that I think I gained a 1/4 inch in girth that has remained. I've been off them for a while but that 1/4 girth remains. Is it possible to make gains without doing the exercises. All that was different was that I was having a lot more erections/sex/masturbation than normal for a few months.
