s... How do I find a girlfriend? Need some help... Decided I need to come out?

ok, so I have known that I am attracted to women almost my whole life. I think it was when I was around 13 that it really hit me though. Since then I have only dated one boy, and it only lasted a week before I cut it off because I felt something was not there for me. I am now almost 16, and I don't really know how to find a girlfriend or come out to my family and friends. I have only told one of my very good friends that I am a , but others of my close freinds kinda know, because of how I am (I have always been butch and casually have made statements and such about my uallity around them) I just have never said it. I feel like it is time for me to go out and find a girl that I can love and cherish, and I know I can take care of her so much better than any man could! I just don't know where to start... I guess I am kind of afraid, because my mom asked me the other day if I was interested in women and I kinda got scared and deflected the question. I have never had a girlfriend, and I don't know how to find one, but I know that I am ready and I want to move on in my life. I want to be able to be in a relationship that I can put all of myself in, and be comfortable in. Please help me.
