I say this, because without shouting reverse sexism or defending, but because I grew up in an era very antagonistic to men and boys. You look at what it took to diagnose ADD, your grandparents called it being a boy. To quote Tyler Durden, "We are a generation of men raised by women." In my case, a woman who told me to not be like my father or uncles a lot of the time.
Aggression, physicality are verboten. The schools I went to for primary and junior high were very antagonistic towards boys. I had to teach myself to be a man. As I said to my fiancee, it took me a long time to realize that I can take control without being controlling, I can be interested without objectifying, etc. And then you get into puberty, and apparently pornography led to becoming a serial killer. So finding women sexually appealing is a bad thing.
I and most men I know did not get this as kids, as teenagers. I was raised in an environment not just to respect women, but that a lot of masculinity is bad.
Flash forward today, so many of my peers are already so docile, so demure, beta or whipped (you pick), they have no idea how to be a man for a woman other than being a welcome mat.
Actually, this is apparently a common dating problem for guys.
