"you like girls, and you like this boy who looks like a girl, so he MUST be a girl"
no, fam, girl, friendo... thats not how attraction works, sadly humans are unable to detect DNA nor see genitals like we have x-ray vision, if the eyes sees what *looks* like a girl, your body WILL treat them like a girl, and straight guys WILL be attracted... thats WHY they are called traps *facepalm*
