Kind of hard to guess what someone really means, being the recipient of a "he said, she said" conversation.

OK, that off, let me say that, in my opinion, after telling her about your nice 'vanilla' relationship, and the fact that you were simply 'curious' to begin with (hey, we ALL should try everything once in life, eh?), she should have respected your thoughts and feelings and let it go at that. Very unprofessional.
