Yeah, I understand what you're saying - and if it were just about enjoying sex as a carnal pleasure, I'd be on the same page with you. It's just she said he's being scary and possibly forcing himself on her, so I wanted to clarify that enjoying sex as a carnal pleasure doesn't mean that sort of behavior is okay. Scaring your partner is not something that falls within the "normal" range of behavior, regardless of how much one enjoys or wants sex.

But I do agree that communication with regards to comfort levels and so on is very important, yes.
