You are not a coward -- you have to know your timeline. I don't know if he's in denial about how you feel, or if he just plain doesn't care.

I would agree with that. He DOESN'T CARE how you feel about it. He wants what he wants when he wants it. I think the fact that you vomited after that first experience would be a fairly telling sign that this is degrading to you. Has he ever voiced any concern or empathy for your feelings ever?
