Just to toss this out, it might not be all kissing you hate. It might be his style of kissing. I've never met a guy who can kiss the way I want to be kissed. They've all been too rough and wet, or at worst, slimy even. Eew!
I found girls, on average, kiss much better. It's cleaner, delicate, and just superior in other ways I'm having a hard time articulating. If kissing a girl is a waltz, kissing a guy is like being in a mosh pit. Again, on average. I knew one guy who was a tolerable kisser, and one woman who just about ate my face.
So, it might not hurt to experiment with kissing differently. Find some fantastic looking kisses in movies, and tell him to try his best to kiss like that. You may be surprised by the results.
