What can I do to stop my boyfriend from thinking of my past?

Ok for those who answer my last question about my boyfriend n my past correctly thx. He has not stop thinking bout it he just doesn't talk bout it any more . I need some ideas to get his mind off it. The guy who took my virginity goes to my school that's wHat makes him think bout it the most. When I c the guy I either get n his face or kiss him until he walks past us. Then the dum crap is that it's like he get a kick out off us stressin ova the bull crap like it funny or something he told half the whole school bout my past but it no big thing we only got 9th and 10th grade but any way that's the problem now. It's lik the guy wants us to c him I mean at first we really didn't c him at all now it's lik where we go he go. But the real reason that my boyfriend doesn't like when his friends or people period to come up to him talking bout it that's what really gets him. If ant body else has problems lik mine I really would lik to know what u did to solve your problem thx
