Right before, I can tell its coming because my sex drive goes through the roof for the two days prior.

During my period! Which is the worst time since I get it less!

Before and during. After I usually start a new pack of pills and that dims my libido a bit.

as i have no period, this has no affect on the matter. however, men do have cycles as well. my own seems to be three weeks on, one week off. typically within that three week period of being on, there is a three day stretch where i should NOT leave the house...girls just walking around, looking sexy, spelling like honey, mouth just watering... you probably have all seen a man in this state, when he just can't function other than to growl or grunt while fighting internaly with the primal urge to rip your clothes off. yeah, i'm on my off week right now. and, in case anyone is wondering, we do not get more done on our off week. i tend to get more done durring my on weeks; trying to distract myself from the nagging desire to get pelvic.

I have never noticed much of a pattern.

before

I'm always super horny right before my period. I don't know why, it must be the change in hormones.

Towards the very end of my period and then right after

right after. I need sex and I need it right now! haha
