I am a bisexual guy, and I have a problem. I have a girlfriend and a major crush on my best male friend, each of them are straight. I have already told my friend about my sexuality and my crush on him, but I am afraid to tell my girlfriend. She is an understanding person, but I think she might think I went bi because of her. How should I tell her? I am pretty paranoid about this, and I haven't even told my parents about my sexuality. Please help me.
