H had been doing some sexual "research" and had something he wanted to try (I'll skip the details.) I said I didn't want to do it because I wasn't comfortable with it at all. He did it anyway, and I felt utterly humiliated. I told him how I felt, asked him to stop, he continued. He loved it, I'll never forget it.
Sorry, but the rest of what you posted is just a blur to me. This is tantamout to marital RAPE (and you'd have to know me, and how much of an "Oh please; we're all way-too-thin-skinned in this country!" guy to know how much this REALLY bothered me), and I'm pretty stunned that o.t.'s advice is as mild as it is in response to it.
This should be a dealbreaker to you, and a HARD boundary needs to be drawn, swift and hard. I'd certainly start with another 6 months of separate bedrooms.
I do have to admit, I haven't read your sitch, so please let me know if I'm reading this wrong, Crazy.
