TAL While its absolutely NOT unreasonable for a man to want to ML 2 or 3 times a week it is easy to see why his behaviour is causing you to lose the desire to participate.
If a man is constantly being verbally abusive then of course she will lose the desire and sex will become undesirable to her. If he is not taking time to arouse you and just using your body then it can be painful.
The resentment you feel over having to do everything alone I understand as my H was the same and he never appreciated how tiring it was for me A little thoughtfulness would have made me more receptive to desiring him. Finding a way to get this across is difficult but not impossible.
The difficulty is knowing whether you changed after the children were born or if he has always been this way. Some men are jealous because the children are the centre of attention and they become just the paycheck.
Not sure what you mean by kinky I mean my friends XH liked to be whipped and wear womens lingerie but didn't have penetration with her. That to me is kinky anything else don't really know unless he enjoys being really rough with you. Playful rough fine butthere is a line between playful and nasty like biting hard is nasty.
