Re: i only get erections when ...
Be careful taking all of their advice. I'm not saying it's bad, but it could land you in a lot of trouble.
Just because we say you might be gay doesn't make it true. You have to really think about it in yourself. Find out if there are any girls that do arouse you, and what their characteristics are. It's also a possibility that you really are just curious, although it would be a stretch to say this.
So, don't go "coming out" to everybody just yet. Give it some time to stew in your own mind before.
