I am an 18 year old healthy women with no sex drive, i have been with my boyfriend for over 4 years now. I was abused by my cousin as a child, i think that might be the problem...

help, what can i do

Many times something traumatic happens...
it could be with sex or with anything...and
it effects everything...

In your case, it seems that you'd need
to talk to a counselor so that you can
overcome your negative feelings.

You'll be alright.

i agree with kaylar. And you are so young and not to be a preacher about it, but maybe it would be better to get your feelings under control before you continue to have sex anyway. Sex is a big responsability in a relationship and when you are young you don't realize all it entales. Take your time and heal your self before you go and give it away. if your boyfriend really loves you he will wait until you are ready...he shouldn't be pushing you anyway. I wish you luck.
