Generally the raging desire to get in another guy's pants is a good indicator. On a more serious note, a lot of it relies a lot on your social context; I "knew" I was gay from about 11 (before puberty), but I didn't acknowledge it until I was 14. There are a lot of people who don't realise/acknowledge their sexuality until they're into their 20s or even later. There are nine year olds who come out, too, which makes me think that most people should know that they're gay, but social circumstances prevent it. Puberty makes it a little harder to stay in the closet to yourself.
Unfortunately, I thought I was straight, having crushes and even masturbating to females, for about a year or so during puberty. Then, something changed and I started thinking about hot boys, including one guy in my class.
A small part of me has known as far back as I could remember, but it wasn't until I was 14 that I actually "got it."
I noticed i liked boys at like 13 but only really acknoledged the fact that it i am probably 85% gay like a few weeks ago ^^
Before I found out, I wanted to look at naked pictures of older men on Google. I didn't know why I wanted to do that, I just did. Then I found porn and that's how I discovered...
I'm not very educated on the topic, but for me it was something like a 'click' that made me realise certain aspects of myself I may have been ignoring.
Mine was a much more gradual process. I liked girls and was curious about other guys at the beginning of puberty, but the pendulum kept swinging toward guys the older I got. I thought I was bi for a long time, but once I finally accepted it and allowed myself to think about dating and checking out and hooking up with guys, that's all I could think about. So at 26 I realized I'm gay.
Ya, shortly around the time that I started puberty, I found that I wanted to :***: other male-bodied people. Naturally, I found this incredibly alarming and proceeded to hide in the closet for two years.
Always knew, though yeah I'd say that puberty made it click. I actually started 'thinking' when I was 13, though I watched BL / GL when I was 11 and found it... entertaining either way.
Mine was about 12 or 13, but didn't have strong sexual desires. Just wasn't into boys and didn't find them attractive in a romantic and sexual sense. I started getting bad crushes on girls in the 9th grade.
