*hugs* I totally understand. My DH was like this for a long time. He has low libido and just in general doesn't climax often, or he does but doesn't ejaculate. Have you considered male g-spot stimulation (stimulation of the prostate)? It always works for my DH. I'm at work now, but I can post more about it when I get home tonight.(Google the Aneros MGX - The best toy on the market for this and my DH loves it. Totally worth the money!)
You could also discuss it with his doctor. Some antidepressants have less effect on libido than others.
Have you guys looked into maybe trying a different antidepressant. There are so many available now that if one isn't right for someone there are other options. Has he discussed this side effect with the doctor? I really hope you get this worked out. Also, have you tried experimenting with different methods and techniques during sex? My DH doesn't last long at all with me on top. You could even end up having some fun trying to figure out a way around the issue. If you feel that it really is impossible due to the meds, have him talk to the doctor about it.
That is such a foreign perspective, to me, for a man to have. My DH would be way more depressed about not being able to O than nearly anything else. Though I suppose if he's still enjoying the experience, he may not necessarily feel deprived. Has he said anything? Is he aware of how you feel about it? I hope you can get him to talk to his doctor about finding a solution. If not, is he willing to do IUI so you can at least get pg?
Sorry, haven't been back to respond due to weather/power and internet outages due to massive flooding our city had two nights ago. I'll try and get online tonight....
Darn pregnancy brain, totally forgot to come back here and post!
Anyway, you might want to try prostate stimulation with your DH if he's willing to try it. The less intensive way is to press on the space just behind the scrotum in the perineum area. This will put pressure on the prostate which is their G spot. I started out learning this when DH wanted to...manually pleasure himself with my help (usually when I'm on AF as I'm not one who likes sex during AF). You start out lightly and then press firmer. You will know when you hit the right spot. Sometimes you need to press slightly towards the base of the scrotum a little to get the right spot.
If your DH is more adventurous, the Aneros anal toy is excellent. He would put it in during foreplay and keep it in during sex, which would work better for TTC purposes. It's guaranteed to give him lots of pleasure and a good O. They have lots of models, but the basic one is fine. My DH has a few different ones including the original Aneros and the Vice (then again, my DH is bisexual and quite open to anything in the bedroom). The website I linked above has lots of information, so check it out.
Feel free to PM me if you have any other questions!
