Being bigender and asexual, I tend to remain neutral, but my male side knows what to do to pick up girls-even though he doesn't feel sexual attraction. But only if I've not taken the Thai herb derris scandens in a while (it blends my gender modes).
In the past, I have suddenly become aware there are giggling girls all around me and we are heading for my place, until my female side wakes up and makes an excuse to exit.
If not suppressed by the herb, my male side cracks jokes with pretty girls, asks them about themselves, shows focused interest, compliments their clothes, oozes casual confidence, and finds a way to mention macho activities, i.e.
"You like Australia too? I love going Outback camel trekking, but Sydney is my favorite city there."
It's apparently hardwired into my male mode, but my female side doesn't flirt with men, or respond to flirting, at all.
