If it's any consolation, I don't associate publicly with anyone that can be considered a furry.
Diamond and Pearl had just come out, and I hung out with the group of 8 boys and 3 girls that brought their DS to school to play Pokemon. We were all mixed between 5th and 8th grade, and there were 1st through 4th graders that hung out with us after school. >how the fuck did you have openly furry friends at age 12
I was in 6th grade (2007/2008), and during lunch, two of the boys and a girl that were in 7th grade ("""Boy 1 & 2, and Girl 1""") were talking about how they fapped to male Pokemon stuff (they were ok with talking about it because we hung out in a "secluded" part of campus so we didn't get our DSlites confiscated, and we had a "what we say doesn't leave the group" rule), and they wouldn't shut up about how much they loved Lucario/Arcanine/Eeveeforms. I knew what a furry was by that time, so I'd tease them for being furries. One day I went to hang out with Boy 2 after school, and while we were looking for battling tips online, he asked if I wanted to look at some other stuff. He showed me some gay Lucario stuff, and like a dumbass, I kept looking for like 15 whole minutes. I still didn't really know what boners were by then, but when I noticed I had one I got really embarrassed and told him I was gonna walk home.
Thankfully he didn't tell Boy1 or Girl1, or anyone else in the group, but he would tease me about it when we were alone.
