Well, as I said in my 2nd post... if you've done it all and nothing changes you may have to make a tough decision.
I've lived in a 10 yr long term with barely any intimacy and I can tell from experience it ruins your sense of self as a woman, trashes your self-confidence, and overall sense of well-being.
In short, it is devastating. I ended up constantly suppressing my sexual energy which means you also suppress your sense of self and expression, creativity, and life-force energy since sexual energy is all that.

I'm glad I'm out of that relationship. Now it's up to me whether I have sex or not. It doesn't hinge on a man having a headache, not wanting, or unable to get it up.
Now it's my choice.
I can tell you that feels a helluva lot better!!
