17yr old guys with 13yr old girls?

I think if your friend found out that you were bi it would be a little awkward since she meets you and everything. I'd say she'd be a bit afraid you were feeling something else and not just doing it for fun... Yeah I'd stop meeting her way before I told her. I know that doesn't really help.

You possibly be bi. It depends. This could be a normal teen thing you want to do!

If you don't want to be bi or lesbian I suggest stop having oral and kissing girls. Some stuff can mess with your mind. You could be straight and like the oral and dreams.

You could just get turned on by it. People get turned on my different things.
