I don’t get this. 11 years and you still haven’t explained to him that you want a different style of sex on occasion.
I would find protracted, slow, intense sex a bit weird and wouldn’t enjoy it. Doesn’t mean I don’t love Dp. I would give it a go if he really wanted (he is the romantic hearts and roses type), but I can’t imagine I would enjoy it. But he would definitely need to take the lead and show me what he wanted.
You, now, asked him a question in a really odd and contradictory way and angry that he answered honestly. Then you saw your arse and got upset with him. He thinks you are over reacting. You think he is gas lighting because he thinks your over reacting.
But you are over reacting because you asked a confusing and contradictory question and then assigned all sorts of feelings to the answer. Not your own feelings. But his feelings. You decided what it meant. Asking people an open question wanting them to give one answer and deciding a lot of meaning that they haven’t said on their actual answer and Telling them what their answer means, emotionally to them, is closer to gas lighting.
He invalidated your feelings. You invalidated his, by telling him how he actually felt.
If you aren’t happy with the quality or type of sex you are having, you need to just tell him.
After all this, you still haven’t told him you are unhappy with your sex life and what you actually want. It’s really odd
