One thing that might be his problem is embarrassment. He might just be embarrassed to talk about these problems with women. People our age (I'm 63) weren't taught to talk about that kind of stuff with our mates -- but since we've become more "with it" -- at least we women have -- we feel more comfortable talking about it. MEN DO NOT. They're still back in the OLD days of keeping quiet about it. So maybe you should give him a break and not take it so personally.

He's just not "up to speed."
I'm glad you're going to see the doctor. When I had my hysterectomy, they also did a bladder tuck and that helped matters. But that was quite a few years ago, and now it seems it's sagging a bit more again, darn it. It's not serious yet, but gravity has definitely set it.

Ohhh the pains of growing old. I'm a widow tho, so sex isn't an issue for me.
I wish you the very best my friend. God bless you and PLEASE let us know how things turn out, will you? We do care about you. Hugs, Lee
