How does a preteen boy know if he is gay?

Hello :)

If you're preteen, chances are, you'll be attracted to the same sex for awhile until you hit puberty. Sometimes you start getting an interest in girls, sometimes he goes for the guys. In my case, I went for the guys :P.

Boys are sometimes attracted to other boys because they feel more secure around boys rather than girls. It is normal to feel aroused upon seeing other naked boys when you are young, as it is something unusual to you.

It isn't until later that they might realize that they actually, in fact, are attracted to girls.
