I am Bisexual and I have known for along time. I have been scared to come out because I was afraid my family and friends would disown me. But belive me it is much better to tell someone than to let it hang on your solders and let it own your life i am very young and I know my sexuality and I am very proud. So if you know you are gay or lesbian or both let someone know. IF YOU ARE READY. But do't use it to get back at someone. Sit down and have a conversation with who ever you are speaking to.
