Is it normal for a 13 year old to have a crush on a 10 year old?

The majority of boys have sexual fantasies about girls or women. Some boys are sexually attracted to other boys. Experts agree that sexual orientation is often fixed by puberty. If this is the case, then it is normal for a gay boy to have fantasies about other boys. The truth is, though, that sexuality is a spectrum and there are individuals who fantasize about both sexes. Keep in mind that fantasizing is not the same as acting on one's fantasies.
