I'm afraid, Poet, you're very naive in that regard.
Him not asking first is part of 'The Game' - it's him knowingly taking advantage of the fact that 'it's easier to ask forgiveness than permission'. If he just does something then his target is more likely to allow it to happen (because women are socially conditioned to not say 'no' in those kinds of situations) than if he asks first.
It's a deliberate tactic meant to override and disregard your boundaries.
There is literally no way that he is under the age of 60 and doesn't know that a man is supposed to ask before trying something new, or gain signs of enthusiastic consent. Add to the fact that he's read 'The Game', which is all about trying negate and avoid a woman saying 'no', and coercing her into sex (raping her), he absolutely knows what he's doing.
He is deliberately inducing a fear/fawn/freeze response in you, Poet, when he does things to you without asking, and he's very successfully groomed you into thinking that an incredibly abusive and unnatural dynamic is normal.
He knows what he's doing. As an older man, he deliberately preyed upon a vulnerable, traumatised teenager, because he knew you'd be easy prey for his tactics. Then he used every trick in the misogynist's handbook to skew your perspective of normal, make you emotionally dependent on him, and keep you pregnant.
I think if you can't bring yourself to name it 'rape', then you should at least try to reframe it in your head as 'coerced sex', and move away from just calling it 'sex'. What he does to you is not what a husband is ever supposed to do to his wife.
