A few years, when I was depressed following the death of someone close to me, a doctor friend suggested I see a psychiatrist for an anti-depressant.

For a few months, I was on a low-dose of Lexapro, an SSRI that's supposed to have fewer side effects than older such drugs.

Not certain it did much for my mood (as many as half of all patients find the SSRIs don'tdo much for them).

But I noticed right away that while my libido was strong as ever and my cock hard as ever, I couldn't cum during intercourse and only with difficulty when my GF sucked me. I had no problems when I masturbated.

As we were using condoms, it was easier for me to pretend to cum and then throw away the used condom than explain why I was having trouble. Since I was still hard, she thought I as superman as we had round after round of sex.

Once I stopped the Lexapro, it took about 10 days for my orgasms to return.
