Well, when I was around 9 years old my best friend and I were staying the night at her house & we really didn't know that "making out" was a sex thing or even bad. Lol. We just heard about it & thought it was cool. So we did! & We had no idea that it was anything to do with love, sex, etc. So we decided it was a neat thing & was so proud that when her mom came home, we said "hey, watch what we can do!" and we made out for her mom! LOL OMG! She freaked and I don't remember if she was angry or not, but we never did that again. We still didn't know why she freaked until we both got older and figured it out.
The, I guess the next experience I ever had with a female was in the 4th grade. It was a best friend of mine (and still is.) we live on the same road and always have so we were always together and very close. I had never heard of oral sex or anything and had no idea about this stuff. I knew what sex was, but never even knew there was a such thing as gay. She told me she wanted to practice kissing for future purposes. Lol so she decided we would watch titanic lol and re-inact it! I didn't know half the things that were going on. All I knew is she was on top of me grinding. Never even knew it was sexual really. She was very horny to be so young! Lol. She always wanted to kiss and stuff and we did a lot.
Then we were in the 6th grade when she'd learned the term "eating out" I THOUGHT it was something she'd made up in her head. Lol I didn't know it really existed. She told me that her and another girlfriend done it to each other. I spent the night with her and the girl who she'd been "eating out" and they wanted me to try it too. I knew it was just not something we should be doing so I didn't get involved, but they did. I kissed the friend of mine still, but wouldn't do the oral sex thing.
Then I guess I was in the 7th grade when I got to know a girl who I was close with for a long time. We had a lot of girlfriends so we kissed all the time. Then her dad got us drink one night (he loved doing that!) and she took it to the next level and we did a little more. Other than that and the just kissing, that's the only same sex stuff I've been involved in.
I guess that is pretty young though.
