It wasn't fun and left me with a lot of self-esteem issues. The tact most women have with shorter men is pretty horrible. They feel free to flat out say what makes a man less masculine, but if a man dares to say what makes a woman less feminine, he's some monster. Before the age of 23/24 I was never even really mad about it, I just figured "that's life". That height is probably the most important thing for women and that youthfulness is the most important thing for men. That as I get older, such attractions will become more and more of a factor. Then I came into contact with the feminist body positive movement. That women being judge for their appearance was "sexist" and that the patriarchy "made up" these things to hurt them. I was flabbergasted with the lack of self-awareness.
Men are constantly shamed by women for not being masculine enough. Body shaming is not a woman only problem. And at this point, for a millennial like me.. why should we treat our female peers any differently than they treated us? I'm sorry, but age really is a important thing for many men. I'm not making this up in order to be "mean" to women. It's ridiculous. Even as a kid, I was well aware that height was important for women (and judging by my father I'd never attain) but that youthfulness was important for men. This isn't something I adopted from the manosphere. It's just the average man naturally feels. It's how we evolved.
That's what really bugs me the most. Women seem to live in a fantasy world about their bodies, while men tend to deal more with reality. They don't always deal with it in the best way (like the incel movement) but we're less prone to deluding ourselves that women don't some of our physical features because of some socially engineered sexism. Society won't give us that, but it will prop up false delusions for women.
