Just to clarify, he didn't ask me a yes or no question. He was assuming he could do what he wanted. He did not ask me not to tell him "if" he could come in me. He asked me to tell him I could come in him. That's where it slipped into BDSM dynamics. Subtext, in context of other requests, was he was asking me to say "you can do what you want because I'm your sex object". Subtext back was "mainly, yes- but remember, we don't have birth control- and that was a predetermined limit- no coming without 2 forms of protection."
