Why are taller men perceived as more masculant by women ?

You are true but probably its on our DNA that the taller guy is more attractive part of evolution, you are correct that high has nothing to do with the lever of testosterone. Its just how we are wired just part of evolution.

because it is intimidating.

They are in many cases, but not always, so...

It's an unfair judgement for sure because there is literally nothing a short man can do about his height, yet it's perfectly normal, accepted and mainstream for women to openly mock or refuse to date men who are under 6 feet tall (and I'm saying this as a 6'2 male so before people assume I'm just a bitter short man, I'm being completely objective here). I often wonder what would happen if men started stating on their online dating profiles "only C cup or larger" or "120 lbs or less". Even though both of those things are things women CAN change (unlike a man's height), everyone of them would be screaming "misogyny"! That's what feminism has done to our culture. Women can do it, men can't. Simple as that.
