Help! He's a bad kisser?!

I started seeing this guy about a month ago whom I have a brief history with from about 3 years ago. Back then, we had sex a handful of times and it was good. He told me he wasn't "ready for a relationship" and I took off. He has been alllll about me ever since and after seeing him out a month ago, we rekindled and went out. We have always gotten along amazingly well. He's super smart, graduating this coming spring and he has a great job lined up. His family has horses and so do i. Not only do we share so much in common, but he definitely puts me on a pedestal. He makes me feel like a total queen-every girls dream right? Plus, he's a total gym rat and he's gorgeous. Except... when he kisses me, I get so uncomfortable! He is too much. Too much pressure, too much tongue, too much heat, too much movement. He gets so aggressive with it that he actually leaves bruises on my lips. Im a pretty petite and gentle person and I can't get with this!! I like this guy a lot and would definitely try a relationship with him. Should I tell him everything that I hate about the way he does things intimately or is there no hope & I should walk?
