100% sure, 100% confident. I don't let anyone shake me down on this, to be honest. I don't deny it if I'm asked, regardless by who. There's no need to hide who I am, I'll let everyone know. I don't understand why straight people can really be uncomfortable with gay people. I mean... are you so unsure of yourself that you might end up making out with them? Really now... use your common sense. You wouldn't want someone, boy or girl, that you weren't attracted to or didn't like kissing up on you, and that's not something I would do, either. So not only am I comfortable with mine, I'm comfortable with all my friends.
I would never deny my sexuality, but I also don't believe in going around shoving it in people's faces. That why I never really "came out." Straight people don't go around going, "I'm straight! I'm straight!!' You know what I mean? I obviously told my friends, the people who would care, my family etc. But I didn't tell people who didn't need to or didn't want to know. It's just... eh... dumb.
