a girlthing

I've noticed that I often go through phases of horny, like for a week or two I'll be super easily turned on and motivated to take pics of myself and stuff like that, and then for 2-3 weeks after I'll masturbate maybe every 2 or 3 days and not watch much porn. I remember reading somewhere that amab people can go through hormone cycles similar to afab people, I wonder if that could have anything to do with it.
