I'm new too. I have, in the past, had this issue (inability to ejaculate) due to medication. I am taking Zoloft and have taken numerous other anti-depressants in the past. I have had sexual problems with all of them.

Doctors are so apathetic to this problem. I went to two doctors about this, hoping that a counter-active medicine (Wellbutrin) would work. I got the Wellbutrin only because I suggested it. It didn't work and I am no longer on it. The doctors I talked to were so unwilling to discuss this problem and acted so weird when I brought it up that I was ashamed for talking about it.

Luckily, I found that this problem has largely dissipated over the years. It's weird, but I think it has a lot to do with having a very patient partner who is willing to take the time to let you re-sensitize. In other words, I think that continuing to have sex helps, even if you can't ejaculate. I believe I retrained my body over time and have had a pretty normal sexual life, despite the medication.

I hope my common experience helps with the anxiety that accompanies this problem. I think the sexual tension sometimes becomes so great that we become very focused on what we're not able to do and we worry about our partner. I used to call myself a sexual tyrannosaurus (ala Jessy Ventura in Predator) because I could last so long. My wife was very patient and loving, and it made a world of difference.

Good luck.
