Hi Inny, I know the only thing to really do is stop, but even then the scars you have now will still be visible. The best thing I can suggest is along the lines of what esqueelio said. Your boyfriend obviously cares about you and he does not want you to hurt yourself. If he cares about you like that, I'm sure he'd love to be able to see you while you two are intimate. If he knows it's there, I'm sure he understands and won't think it's gross or weird or anything. You should, while trying to stop cutting, try to accept that it's okay and like esqueelio said, it's just part of you, not all of you, and surely your boyfriend can see past them.
