The only “thing” that happened was me and my friend making out. I was 15 at the time so my hormones were raging. And when you get the sex talk as kid, it’s usually about sex with the other gender, not the same, so I wasn’t privy to the facts of sex with a female.
Well, she wasn’t lesbian. And no, not really. She had been struggling with her sexuality for a while, so she asked if I could kiss her and see if she enjoyed it. She it felt weird but no bad. She’s straight now.
