how and when did you find out your sexuality?

Here's my story.

Sometime in April a guy who was a friend of a friend started touching me, yes I know I should have not let this happen but I found him kinda hot so I let him touch me. Started questioning when I got home. I then developed a slight crush on him but got over it after a few weeks. At this point I figured out that I might be bi. I'm currently questioning what label of bi I fall under. I might be omni or just plain old bi

I should have handled the situation differently but it caused me to learn about myself.
