You SHOULDbe making a big deal out of this, it is a very horrible, nasty, demeaning, controlling form of sexual assault. Repeated sexual assault. It is not happening because you are not having enough sex,nor for any other reason to do with you. It is happening because he does not see you as fully human, you are just a warm series of sex holes that he believes heshould have the right to do to as he pleases.
I also reckon he is punishing you for not having anal sex. Not that you should, of course.
It's also very humiliating and violating, isn't it, having him put his finger up your bum? Don't delude yourself that he doesn't realise this; this will be the lrecise thing that he gets a kick out of it, that keeps him doing it. Many abusers are perfectly pleasant in all areas except sexually - they know that it is so hard for women to reconcile their nice, helpful partner in the day with theman who ocassionally does weird, cruel, awful, abusive things in the bedroom. They know it makes it so hard for you to tell people, that you'dnever dare tell people what he does if you left him, etc.
It's not even just the act, which is vile enough as it is. It's what him doing this saysabout who he truly is, deep down. About how he views you, and women. About whepat he believes he is entitled to do to you. About how his sexual kinks matter more to him than your pain or indignity or humiliation. Andsticking a finger somewhere isn't that much fun for the person doing it, it's meant to be for the pleasure of the person on the receiving end. Whichis why this is all about him getting off on demeaming you.
You say you have 2Dc - do you have a son? How would you feel about him treating a woman this way when he'sgrown? Because he'sgrowing up with a father who finds it accaptable. He doesn't need to know ithappens for the attitude of aman who could do that to rub off on him. And do you have a DD? How do you feel about a man doing this to her when she's a woman? Would it be okay?would you tell her to leave?if so, why is it okay for you to stay?! Growing up with a father like that will damage her.
