Well, as your sister, I was going to say something like RUgreek but obviously in a much nicer way.
Don't go near this guy again. All he wants is sex. ALL HE WANTS IS SEX. And if you don't want to have sex with a guy who isn't your boyfriend, then don't compromise for this guy who isn't going to make you happy.
I'm sure he's lots of fun. One of my friends back in junior high/high school was lots of fun, but she treated me and another girl like dirt and was always talking shit about us behind our backs, and finally tried to steal both of our boyfriends at once. I cut off all contact with her, because I realized that being fun to be around wasn't worth all the other crap I had to deal with. THIS GUY ISN'T WORTH IT. Fun /= Happy.
And P.S. Don't listen to anything that James tells you regarding relationships.
