I wouldnt do it...the guy sounds like a player...and for him to tell you about all of these things right away sounds like...he's proud of them or something.
an attraction to bad boys is fine...don't get me wrong....buuut I do agree with david...If he cared about the girls feelings and actually KNEW what love was...he wouldn't have said "wen ur in love n u wanna have sex..." That's just unbelievable I can't believe he said that. It almost sounds like he was looking for confirmation from you to see if you agreed.....
He sounds like bad news to me...but whatever you decide I wish you the best of luck!
