How can I come out without saying "I'm gay"?

I'm a sophomore in high school and being in the closet is eating me up inside.I see the way my friends and family talk about and treat gay people (which is the reason why I've been in the closet), but I can't stand living a lie anymore. A part of me wants people to know, but I don't have the guts to come out. Is there any way to subtly hint at or let people know that I'm gay without saying it. btw I don't act effeminate and I'm always getting hit on by girls so I'm pretty sure no one already knows that I'm gay.
