Is it weird for a man to want to look young and skinny, not toned and muscular?

Throughout my life, I was kind of lightweight for a guy. When I was in 12th Grade in high school, I was 123 pounds--maybe 128 pounds towards the end of my senior year. I knew that the ideal physique for teen boys and men is toned or muscular, but I never wanted that for myself. I personally didn't care for it.

Another thing is, I'm 5'6, so I'm short for an American man. And because of that (and me constantly shaving my mustache), most people mistake me for a teenage boy. So if someone looked at me, they'd probably think I was in high school. I actually like my youthful appearance, even if one of the reasons for that makes me unattractive to most women.

I guess this is kind of a beauty standard in South Korea and maybe Japan, I dunno. From what I heard some women from those countries like their men skinny and really young-looking. Kind of like the K-Pop group BTS. Seriously, look at them! These guys look like they're still in high school, and they have millions of women and teenage girls simping for them.

And I'm not even Asian. I'm an African-American. But this "pretty boy" or "bishonen" look seems to be popular in those countries--or at least South Korea. Despite being black and American, I like that beauty standard, and I'd rather live up to that than have muscle tone.

Is it weird for a man to want to look skinny and very young? Also, ladies, what do you think about men like that?
