So I was at a friend's house. 4 of us, 2 boys 1 girl. 1 girl and 1 boy left the house to go for a walk. I was resting with my head on the other boys chest. Not in a sexual way at all. He had been flirting with me a bit here and therwe, but nothing really. When they left we began talking and it ended with me saying I've never been kissed by a boy. then he kissed me. And he used a lot of tongue. A lot. And we made out for a good 10 minutes. It involved him trying to get into my pants a bit and feeling up my boobs. It wasn't good. there was no spark. It wasn't like it is with a girl. Here's a few other things things mention- I hadn't had physical contact like that with someone else for over a year. I was desperately missing it. Earlier in the night someone had been giving me shit for how could I know I was a lesbian if I'd never done anything with a guy and such. I didn't like it. I feel like a "bad lesbian". Can I still even call my self a lesbian? I have zero feelings for this boy and would not do it again. But now I can't stop thinking and judging myself.
Just because you kiss a boy doesn't change who you're attracted to, so of course you're still a lesbian. Everyone experiments. You tried something, it clearly sucked.... so that's something you know you don't like and can move on to other things.
If you can make out for 10 minutes and not feel the spark, this confirms that you are gay. A good lesbian. (Or at the very least, that you are not straight for this guy.) If I were you, I probably would have done the same thing. And come out saying "Yuk! Can I kiss a girl to wipe that off?" Let's hope you can soon. This might be weird, but I'm kinda proud of you for trying.
Hey it doesn't make you a bad lesbian, don't ever let anyone tell you that. Sounds like it confirmed what you already knew. I am assuming it was a straight person that said you couldn't know you were a lesbian unless you had been with a guy, if so next time just ask them how they know they aren't bisexual if they haven't been with the same sex.
