Trouble Getting Off

Hey, girls. I'm a long time user of <a href="">Eve</a>, but this is my first post. Can you help me out? My boyfriend and I have been together for a year now. He's amazing, I love him to death, and the sex is good, but here's the problem: He refuses to go near my vagina with anything other than his penis. I've told him constantly that I can't really get off without clitoral stimulation, and he seems sympathetic, but he keeps saying he had a very bad experience when he was younger with a woman who did not take care of her hygiene in that department. He says he's trying to work through it, but, even though our sexcapades are fun and feel good, I'm left hot and heavy after he's finished. I can't even touch myself during because he explained to me that it makes him feel immasculated, and I don't wanna do that. What do you girls suggest?
