I have tried and tried in every place to find out what exactly it is (specifically) that makes women, and especially girls, feel they are "really" men? Does anyone have any idea? I am a man and would love to know what, apart from some very general conviction (asserted but never made specific); wanting to wear male clothing; wanting male "body shape"; represents becoming a "man" to trans women (or girls). Such ideas are supposed to match the reality of having a male identity. I do not have any supposed cis-gender identity, but I know what things have been central to living as a boy and then a man - and it's nothing like anything I have read about trans men. I never thought being a man depended on others seeing me as man; I never thought about my body shape; most of the clothes I wear (and have always worn) are very ordinary and could just as easily have been worn by a woman. The big big deal for me all my life (I am in my 60s) has been the way I experience sexual excitement and arousal: my body will register it (and sometimes against my wishes) through penile erection; the next has been the experience of orgasm deep in my body (prostate gland); then how vulnerable to attack (friendly or violenbt) by other males, or my own clumsiness, my testicles made and make me. Only then came comparisons - I was aware of, generally to a high degree, being taller and stronger than females. Finally, I learned that I could become a father (with a growing realistion I was expected to do so); that I had a distribution of body hair (more than some other men and less than others) that affected my appearance. It seems to me that even if you think you are a man, you have no idea what being a man is like unless you are one. Hence nobody ever says. Anyone able to help with ideas?
