My gender swings a bit, but it doesn't appear to be tied to my menstrual cycle. My romantic identity however, is intensely tied to my gender identity (if I'm feeling more male, I'm attracted solely to males; if I'm feeling more female, I'm attracted solely to females). Anyway, my gender just kind of swings throughout a month or two or even sometimes fairly quick like within an hour. It's a bit annoying since I can't pass as male and if I cut my hair I look like an ugly girl so that doesn't help me. I just deal with it by writing a lot. It's started to balance things out more with me, at least emotionally.
