Waiting Until Marriage

My boyfriend and I have been dating for a while and he wants to wait til marriage to have sex. Before I was okay with it but now I'm conflicted. He's giving amazing head and I never want to stop just there. I try to make a move and he always says I'm "too pure" and he doesn't want to mess that up. He's had sex before but I haven't. I really want to share that experience with him and he's too fine to wait until wedding night. What should I do??
