Problems Getting Turned On :(

I've been with my boyfriend (he's 24 and I'm 22) for 2 years now but we've only been having sex for almost a year now but recently we've been having trouble getting me turned on for sex. I usually feel bad because he wants to have sex and I'm dry and he tries manually stimulate me (clitoris) and it just feels uncomfortable. I think it might be that I'm not enthusiastic about having sex with him because I only get an orgasm about like 5% of the time. I told him that he needs to be more romantic and caress me more. Could it be that he doesn't turn me on anymore? Or does he just need to look up foreplay ideas? :(
