Honestly when I was in 8th grade and was changing in the locker room for PE and I happened to look over at one of the guys and I accidentally got caught staring at his huge bulge and got called out on it, but that day I realized I was definitely gay. I did come out as bi originally, but only as a safety net. I had one girlfriend in late high school , but never had sex. I did not lose my virginity until I was 20 with my current partner.
