Why are there so many BLs?

[ZeroXJoker]

As a BL,, I'd say that boys have an attractiveness and charm that they lose as they get older. While there are cases of adult men who remain attractive in their late 20s and up, I'd say the ratio of that is lower than in women, and yet they're still not as attractive as they were during their teen years and younger.
Boys are really beautiful, the androgyny that youth gives them certainly helps, I think.

Also a BL I do have to agree with you. Boys are just so adorable and while I do find some of those things you mention in men boys are just so cute in a way that adult men are not. Like just everything about them is so great. I'm also a GL but women in general its different that attractiveness and being adorable is there regardless if they are a girl or an adult.
