I am a healthy 20 yr old college student, I am in shape, eat well, and am doing fine in my classes...I am not significantly stressed. My boyfriend of over a year and I have been sexually active (safely) for about 8 months. But this month, I have had completely no desire to sleep with him. Actually, I get this very sick, nauseous feeling whenever he starts to touch me in sensual areas or tries to make a move. He is very respectful, when I tell him I just am not in the mood or that it doesn't feel good, he stops. But I feel really guilty and sad about it. I don't know what is wrong with me. I suspect a large part of it is that I was sexually abused when I was younger, and although I got counseling and haven't had a problem with sexual desire for several years, it has suddenly come back: whenever I am in a sensual situation with my boyfriend, I just feel numb and sick like I did then. I am really confused. I don't know what to do.Please help
