holy crap! i get the same thing! if i don't initiate, i'll get it once a month--assuming that everything is cleared away: no arguments, kids are good, etc. i sometimes tell her that she needs to be kept like veal--in a box so nothing from the outside world affects her in a negative way! they don't understand that we also need to feel desired and to hear that they love us, and that it's not all about sex. that's the thing: they think it's all about sex, as if wanting sex is filthy! my wife will give me oral and allow me to give it to her depending upon the time of the month. in other words, 6-12 days after her period is the time for me to have mind-blowing sex (no pun intended). i can get her so worked up that it sometimes only leads to oral and hand manipulation. but once that window of opportunity passes, my month is over. i can't even talk or try to have sex with her. i have tried everything and still can't win. i think it's time for us to start doing things we want without them, without trying to gain rewards, showing them that we can be without them. let them see how it is. maybe that's the solution: showing independence like it was in the beginning when you and she/ my wife and i didn't know when we were going to see or speak to each other again, waiting for that phone call, being appreciated and respected. maybe showing independence will lead to them wanting us, and doing more for us. maybe then we will stop being taken advantage of, because that's what it comes down to: being taken advantage of.
as for your wife not giving you oral sex, i don't know what to say. if she has never done it to you anywhere in your relationship, then i don't see her ever doing it, because she is now set in her ways, and odds are she isn't going to change, because i don't think they want to, because they always feel that they are never incorrect.
