Fear of intimacy during sex?

[Ashley]

I've been with my boyfriend for over a year now. We have sex a lot but I don't enjoy it as much as he does. When he tries to turn me on I like can't get in the mood cuz i worry too much. I get in the mood but its like I have to fight myself to try and get turned on. My boyfriend is really romantic and tries to help me relax but its still hard. I just always feel stupid trying to act sexy. I know I have no reason to but I just feel akward before and during sex. I'm very pretty, thin but still shapely, everything on me is in excellent condition, don't make any abnormal noises during sex, don't have any relationship problems, never got raped, only had sex with one other guy. Just like insecure for no reason I guess. Please help. If u need more info let me know n ill contact u.
