As a 19 year old guy suffering from depression and just recently put on anti-depressants, I found a problem with this side effect. A big problem, kind of...y'know, given the whole late adolescent male teenage hormone thing. :-P When I first started having the problems (decreased sex drive, prolongued orgasm, etc), he told me they'd go away after a while. By and large, they did, at least for me. However, I've got a friend who had very similar problems and his didn't go away. It got to the point where he switched medications to Wellbutrin, which, as I understand it, was engineered, among other things, to get rid of that kind of problem. It really worked for him, so...maybe that's an idea. I hope it works out for you -- of all the side effects I had when I started my medication, I'd consider the sexual ones the strangest and most annoying.
