I didnt realize until I was in my early 20s. In hindsight, I had a few little crushes before that, but it was easy to tell myself "well, I like women, so obviously I'm not gay" while conveniently forgetting that bisexuality exists.

I was on a hiking trip with my best friend of a few years and he jokingly suggested we cuddle in his hammock shortly after we set up camp for the evening. I got a little flustered from it, enough to realize that the feelings I had for him were more than just bros being bros. Luckily he was only half joking when he suggested it, because I took him up on the offer and thats how he became my boyfriend.
