I’ve actually come to a similar conclusion to this myself. One thing I have observed over my lifetime as a woman is that most men think they are masculine (or maybe “tough” is a better word). I can not get over how many less-than-masculine men I have heard make fun of other men for being wimps. I think the existence of testosterone in men makes them feel masculine even if they are not. I’m a photographer and I always hear beautiful women talk about how unattractive they are, but guys almost always seem confident about how they look.
You know there is a saying as old as I am: Women will have achieved equality when they can look in the mirror, see a pot belly, stained t-shirt, and thinning hair, but still say, “Damn, I’m sexy.”
Studies find most men think they are above average in looks, intelligence, driving skills, personality, investing ability, “endowment”, and various other traits.
Testosterone appears to be an across-the-board distorter of personal truths.
