Tonight I gave up

Tonight I gave up TTC. I'm 33 and my husband is 35. TTC for 2 years, no children, no miscarriages, just nothing happened. Both checked by doctors, he has very low sperm count and motility, but otherwise ok (even testosterone and hormones), I am fine. First months of TTC were kind of fun and excitement.. For this past year, it has been really difficult. Opks and everything. We tried not to try too much, I guess we failed. It is very difficult even to have sex. He can't when I initiate (I don't tell him I am ovulating) and even when he starts (once in a week, sometimes two), it it difficult for him to keep it up or finish - and I am not enjoying it - just thinking if he will finish this time or not... I tried everything, wearing sexy underwear, watching porn with him, pretend I am indifferent, massages, nothing seems to work, giving him vitamins, Maca...

We have been together for 10 years, so maybe that's the problem??

I know we have very slim chances of conceiving naturally, but without sex I guess the chances are zero. I am super frustrated and tonight suggested a break, no sex at at all. I just can't go on. 😔
