Horniest Part of my Cycle

People (ahem, men) are often curious what part of women's cycles leave us the horniest. It seems to vary from one woman to the next, but I tend to be horniest right BEFORE my period, when I have pre-menstrual syndrome.

When I have PMS I often find myself in a very agitated and angry state of arousal. If I get too stimulated and aroused at this point, I truly get the feeling that I will FREAK OUT if I do not have an orgasm. It's the time of the month when I feel the most like rough sex, and I don't mean that *I* want to be treated roughly, but that I want to treat my lover roughly.

Now that I'm on the pill my "cycle" is pretty much nonexistent since the pill regulates your hormones so there aren't real cyclical fluctuations. As a result, I don't notice a real difference from one week to the next. During the "off" week when I'm flowing and not taking any pills, I do seem to initiate sex more often, usually after the first couple of days when I'm not really flowing. Then when we fuck I start bleeding again, often a bright red. I wonder what kind of chemical reaction my boyfriend's semen has inside me with my menstrual fluid and if that is what causes the blood to look so "fresh" and almost koolaid colored? Other times, if I really am at the end of my period days the combination of his cum and my scanty residual uterine debris is really gross looking with a few blobs of beige floating in a limpid puddle of spooge.
