I would honestly evaluate what it is about this guy that made you willing up to now to do such things with him in particular. I haven't read all of your replies and posts but from what little I know he seems like a guy that values the female he has sex with, very little. I'm not saying it's your fault in any way but is there something about that type of situation that you might be drawn to it? I dunno about past relationships but I'd look at those too, were they similar or was this a non sequitor with relationships? Some things to think about because if there's something about it that drew you to such a situation, it might be a good thing to figure out why if not... just move on and look for guys that would treat you with respect whether or not it's a casual or full on relationship.
