Yes, multiple times.

Most of them under the influence of alcohol and from the cheering on of males.

Let's make out!! ;];]

Yeah, most recent time: This chick and I were hanging out with her boyfriend, we wanted to make out to piss him off, so we did. She was bad, though. And it was like 3 seconds. She said I was 'kinky' or whatever, but I didn't even get to get good yet!! 

Yeah. I've kissed two girls. We wanted to. (I'm bi.)
Okay... Many details. (Nothing nasty)

first:

There's this girl, Ria. Before I came out, we were at the mall and she pulled me aside and....

Ria: Julia, are you bi?
Me: Uhh.. yeah.. how'd you know?
Ria: I didn't. I just wanted to know because I really wanna hook up with a chick.

I didn't really like her like that or anything, but I had never hooked up with a chick and I really wanted the experiance. We went behind the movie theater and hooked up. There was this guy Rob that was there and watching and I hooked up with him afterward. But it was pretty good.
second:

I met this girl Alyssa. The way I met her was I saw her at the mall and she was hanging out with some people I like to chill with. I walked up to her and...

Me: Hi. I think you're really hott.
Aly: Hey. Thanks. I'm bi too, if it makes you feel any better.

I didn't feel rejected or anything. But later, we were hanging out.

This guy that I used to hook up with, Spike, picked me up really high and when Aly passed, she smacked my ass. Later, she just randomly came up to me and did a booty drop up my leg. Okay.. dude... pure torture. She's sooo hott. Then later, we took a pic together where she had her leg up around my waste. Okay.. that really turned me on. (Hey, you asked for details). Later, when the mall was closing and I was leaving to go to my dad's car, I decided that I wanted to take the chance and there was no point in not hooking up with her. I turned around, dropped my bag and went up to her boyfriend.

Me: I really wanna hook up with Aly. I just wanted to ask your permission if.. she wants to.
Bf: *shrugs* I don't care. *moves out of the way*
Aly: *steps twards me*
Me & Aly: *hooks up*

She's a damn good kisser.
Next day...

I was at a highschool football game and I was walking to the snack bar and I saw Aly working behind there. I just stood there looking at her. She saw me and she mouthed "Come back later," (Or something like that). So I went back later and she was talking to a friend. Aly, her friend, and I went to an area off school grounds so they could smoke (Aly is a junior and her friend was in college). I don't smoke but I went to chill. Her friend left and we talked for a while and when we were going to go, I leaned over and I was just like "Can I do something first?" and of course, she said yes and we hooked up again.
I got her number later and.............
Next day:

We made plans to meet up at the mall with my friend JT. When we were at Popeye's I went up to her and grabbed her hips and I was like "I wanna hook up with you soo f*cking bad." She said we'd go outside to eat and then we could hook up. While I was waiting in line, again, she came up to me and did another booty drop up my legs. So.. F*cking.. Hott.
So after we ate, JT's mom was at the mall to pick him up and I was walking Aly to the exit where her mom was going to pick her up. She went around behind me to throw something out and I didn't notice so I kept walking. She's like...

Aly: Julia, come here.
Me: *turns around and walks to her*
Aly: One kiss before I leave?
Me & Aly: *hooks up... again*

Haha. It was so hott but there were these grannies right there. Then.... as I was walking out I saw JT's little sister and she just stared at me. I was just like "oooooh.... sh!t." So I just rand. She saw me and Aly and I just ran for it because I really didn't feel like explaining it.

My gay and stupid friend JT made her notice.

They walked passed us and he was like "Julie! [JT's sister] Don't look!"

Okay.. no shit she's going to look. So she saw. But it was sooooooooooo f*cking funny.
Well, that's it for me.
