How can I lower my sex drive (female)?

Are there any foods to eat or avoid or herbal remedies or certain types of exercise or anything you can think of that can reduce a lady's sex drive? Or is it just learning to control your own mind? I know that sex is healthy but I always always always end up getting hurt (and I'm pretty picky with who I sleep with!) I turn into a horrendous flirt when I'm drunk and usually embarrass myself. I've become scared of having sex with anybody new but my sex drive is raging! It's probably normal for my age but I wish I could clear my head of boys and fantasy and just get on with my own life. Drives me insane....
