I think I'm lesbian?

Only one way to find out if you are Lesbian. Go out on a date with a Lesbian and see how you feel during and after the date. If you decide you made a mistake, you can leave any time you want. Your date won't hold you prisoner or rape you.

No one can tell you if you're a lesbian any more than anyone can go up to you and say "You're hungry! Now go eat!" and you'll go eat like you haven't eaten in days.

You 'like' girls. So maybe you're a lesbian. Or not.

One ex of mine said she was 100% sure she was gay til she hit 16, met her then-boyfriend, and suddenly it was all about guys. She still fantasizes about women every so often, but she's never gone back into any girl-girl relationships since she gave them up at 16. And she's in her late 20s now. Not to say she won't go back later, but no one can go up to her & say "No no no, you're les. Now get back to the girls!" or "Nope! You had kids with a guy, you're straight!"

Just know that only you can define you. And once you define yourself, nobody but you can change that. One of my best les friends turned her back on loving girls when she turned 25 and began to think her sexual orientation was wrong. She'd known she was gay since she was 8 but suddenly the began to think she should be with a guy. She'd been with guys before and each time, as she lay there with the guy getting his rocks off, she knew "Yeaah...I'm gay...".

Luckily for her happiness she found the right girl.

Couldn't convince her any way that she's anything but a les! ;)

You figure out your sexual orientation not by how appealing you find the look of either gender's genitals but by looking at individuals of either gender and seeing how your heart feels. Which gender makes your heart pound the most? When you look at guys, been on dates with guys, or were having sex with guys, do you have any feeling like you could see yourself spending the rest of your life with that guy? Do you ever look at any girls and feel so attracted to them (physically and emotionally) you could see yourself spending the rest of your life with her? It's all about who you feel the most attracted to overall and most easily fall in love with. When you were dating those guys, did you just love them or did you truly feel in love with them? These are a lot of questions only you can answer.

You don't need to date other girls to know whether or not you're lesbian or bisexual. Look at all the heterosexual people who were attracted to and desired dating someone of the opposite sex without ever having been on a date with someone of the opposite sex. They already knew in their hearts they were heterosexual, and the same goes for those who are homosexual. Any doubts you're feeling are probably from socially-imposed reluctance to be confident to be lesbian or bisexual.

Speaking of socially-imposed things, your aversion to the sight of a naked guy or his penis is probably from the social conditioning you grew up with that imposes a sense of embarrassment, shame, and awkwardness on people regarding genitals and the naked body. It's not a natural instinct to dislike the sight of genitals or nudity. It's probably just a matter that you need to overcome your discomfort about seeing nudity and see the naked individual as a whole person rather than just naked body parts, and see the genitals as a natural and beautiful body part that has a form and function as unique and important as any other part of the body. Another question to ask yourself is, how do you feel about seeing girls nude or the specific sight of breasts and female genitals?

The more important advice I have for you is to always be true to yourself since nobody else in the world knows your true thoughts and feelings or is living your life for you, and to always be accepting and proud of who you are no matter what you discover yourself and your sexual orientation to be. Don't try to define yourself with labels. Instead, just be YOU and pursue whoever it is you're attracted to whether that means a guy, a girl, or both. If you do meet and fall in love with a girl, date her and be in love with her as proudly as you would with a guy. Love is a beautiful thing and if you can achieve it with someone, regardless of their gender, that's something to be admired.

Just do what makes you happy. Maybe try a dating site or something? Don't be ashamed to publicise it either, if you have facebook, change your preference to women x

What is even the question here if you just answered it yourself

Sounds like you are or maybe Bi.
