How did you learn about your sexuality?

I am I bisexual. I haven't told my family yet... That's because I'm only 13 and I don't really want to tell them that I'm dating people already. I knew I was bisexual when a girl wrong my hobby wanted to date me. I was 12 at the time and i have had couple of boyfriend's so I said yes. She was tow years older than me but it was all right. At first it was kinda weird because she was actually lesbian and I didn't really know how to date girls (and I was still young) but I got used to it. We broke up tree months later because she moved but I was still happy and I have had couple of girl- and boyfriends after that too. You might think "well it isn't really love yet because there isn't eny sex it's just kissing" but you are wrong! It actual love because we don't need sex! All we need is to spend time together, study together and support from each other so the love I have for my partner's is real! What is your sexuality and how did you learn about it?
