My wife of 11 years has been slowly cutting off sex for the last 2+ years. We are now down to less than 1 time a month and the sex is terrible, just fucking terrible. She lays there and tolerates me basically violating her. She is begrudgingly giving me pity sex. I used to ask for it and whine about not getting enough until I started reading Married Man Sex Life Primer (2011). I've been hitting the gym and have been approached very aggressively by women in 5 or 6 SMV category. I am probably just going to leave the marriage but she is absolutely wonderful in every other category. I literally have the no-drama wife aside from this. More importantly, I fucked this up. I slowly removed any level of alpha I had and I have probably deteriorated from an 8 to a 3. I believe sex could increase now that I'm not a complete pussy and because I stopped pining over her so much.

First:

I wanted to know if there are any good books/literature/tutorials on how to wow her once we initiate sex. My beta syndrome takes over and I start soft kissing and making love BS. She really just wants to be fucked hard by the Alpha she thought she married. Her comment after our first fuck (before we were married) was "Wow, you were so gentle, I wasn't expecting that" <- I said "thanks." Really it was my accidental alpha ways that landed a fuck on the first date. Pathetic, I know. I now get approached a lot and all her friends are drenching their panties to fuck me. I make an obscene amount of money, and have a powerful career. I know now this is all useless without sexual, or any, game.

Second:

Should I decline sex? According to her, I am getting some tomorrow (the day after Valentine's Day). I'm not sure how to handle that. All I know is that the sex is not good enough to give her the power she thinks she gets by giving me these scraps.

Finally:

Could I even re-spark this marriage, or am I just wasting my time? She is a great roommate and a divorce sound annoying. Please Advise

EDIT: Thanks for all the great advice. I'm really happy I came here.
