Is it normal not to want to be choked during sex?
My ex used to like to put his hands around my neck and squeeze firmly whenever I got on top during sex even though it made me uncomfortable. He had a thing about getting turned on by extreme female submissiveness...well, at least I thought it was extreme and it scared me and freaked me out. While I suspect I'm not alone in finding that scary, he did try to convince me that it was perfectly normal and routine behavior. Note: none of my other lovers did that.
