My wife hates sex. She hates dealing with my cock, cum, anything.
She has always hated to fuck. She faked it for years, because she wanted to be married and ruin my life
I thought that it was me for a long time. I tried everything that she suggested. She didn't try anything I suggested. Gradually, I figured it out. She just hates everything about sex.
I actually used to like the woman, so we stayed together.
I decided long ago, that if I ever got the chance to fuck someone else, I would be on them so fast that their head would spin. A regular would be perfect. I would even pay on a regular basis if I could find a whore.
So my advice would be to go fuck the other woman. Don't tell the wife. She doesn't need to know and will probably be happy that you are no longer bothering her about it, and you seem happier and more relaxed.
