I'm a male, early 20s.

When I was on paxil, I could not orgasm for almost 3 months. Then when I did orgasm it took longer, like 40-120 minutes to reach orgasm.

When I was on prozac I would last 40-60 minutes.

Depending on the SSRI, different effects on different people. I suffered from premature ejaculation, thanks to the side effects of antidepressants I was able to satisfy my parents in more than one way.
