It's not an easy transition- which is a good reason why a lot of lesbians are so obviously "lesbian looking" (whatever that means).

Personal tangent:
I realized that I liked women when I was 15/16 and have more or less identified as queer/bi since then. However- about two years ago I went through a period of time where I only wanted to date women, and really struggled trying to figure out how to make that outwardly obvious. My style has always been a bit tomboyish with a feminine side. I have short hair and tend to wear a lot of jeans with flats or kitten heels and simple shirts. And while during that period of time I was more prone to dress a little more on the tomboyish side- I never gave up my femininity. I like women because they're WOMEN- and thus I never felt like I needed to drastically change my appearance to fit what a lesbian "should" look like. The thing that worked the most for me? Just telling people- mostly my friends- that I was interested in dating women. It was like this weird door opened and suddenly a large number of my friends were gorgeous lesbians. A lot more people have "gay" tendencies than you'd think. I've hooked up with just as many "straight" girls as I have "lesbians", and I have always found that personality hands down counts for more than anything else. Although it definitely helps if you're hot :) Another thing- I found that a sad number of women were very fickle about me, knowing that I had a past history with men. Instead of learning to hide that about myself- I learned to avoid those women. Love is love is love.

Advice for you? Be open about what you're looking for. Don't change or lie about who you are just to fit a stereotype. When it comes to coming on to women or trying to figure out if they're interested- just act as though you would if you were interested in a man. Make flirty eyes at them, touch them when you don't need to (not like that!), smile a lot, mention that you're single. If you're interested in a women and don't know if she's into you or not- single her out and sit down and talk to her for a while. It's okay to drop hints about your sexuality or sexual interest if it is relevant to a conversation. That alone can be a key factor. Just be confident and open and if she's interested she'll make it known.

On the sexual inexperience note- you have a vagina, don't you? You know how it works, what feels good, how to touch yourself, and what it takes to make yourself come. Every woman is different- but you AREN'T inexperienced if you know how to get yourself off. Every woman I've ever slept with has had an orgasm, except for the first one- and that's because she was nutso and wouldn't let me touch her. If you don't know how to touch someone- then all you have to do is ask them how they like it. Sex is fun, even when it's new.
