Friends Boner

I was at school today and I have second period math. At the end we could talk so my friend got up and moved to were I was sitting. When he got up I saw his boner through his pants. I wonder what he was thinking about? I was thinking to myself that it was small. I also noticed that he was trying to cover it up. When I saw that I got a boner. For some reason it was stuck in my head all day and I kept getting boners thinking about it. When I got home I jacked off thinking about seeing his boner. I also dreamed about jacking off together. I don't think I'm gay because I want to have a girlfriend and I like to talk to them more than guys.
