I’m a little sick of people ripping on guys in this situation. It doesn’t mean he didn’t think you’re beautiful, he may well have. The point is that he felt his words were adding to the mutual enjoyment of the moment. He suspected (and for most girls, this is often correct) that a certain amount of mental connection added to your arousal, or at least, it was something that turned him on to say. Maybe he meant it, maybe he didn’t. It’s a mutually accepted non-committed fling. It’s fake by nature. He was passionate, and you enjoyed it. Isn’t that what you wanted?
Why do you believe that, even if he was being sincere, that it would mean he should be interested in more than the one night stand? Some people are just passionate lovers. It’s a good thing, right? Wasn’t the moment that much more enjoyable because of it? If you’d like to pursue more, talk to him plainly and find out his feelings. If you feel that he should or shouldn’t feel one way or the other based upon the experience of a single sexual encounter, that’s your own fault.
