I don't know what to think. I can understand your embarrassment, although you did nothing "wrong" or "unmoral" because during sex humans bring out the wildest part of their being. The point is Panini's behavior: nobody here can give you an opinion about it without doubt because nobody has seen how he was making impressions of you. Did he make them just with sarcasm (as I understood by your descripion) or with a little bit of frustration? In this last case he was, though not completely, right to do so; I mean, he was waiting for your boyfriend to open the door of his own house, I'd be more worried about this sort of disrespect than about he heard me screaming things that everyone screams while making love. This is, of course, my own opinion or I should say, because of what I already said, a "supposition".
