Actually I came out fairly recently, but I had been fighting with the thought for maybe since I was 16. Although now that I look back, I can see signs as early as when I was about maybe 5 or 6. I remember my mother had this cards with muscular guys on the side and I remember looking at them in some kind of amazement or something.
I had finally accepted that I liked guys in august of 09, after a shower scene from the show eureka ( the main character kept going back in time and he kept appearing in the shower, and I think he's hot so..) I didn't tell anyone until mid november, and the first person that I told was in fact a good internet friend of mine. I eventually told my neighbor on his forum and he told my sister, and then on thanksgiving I had a talk with my aunt. And I told my aunt to tell my mother and my mother to tell my dad
Then some of my relatives and friends that live far away from me, I just told them on facebook :P
It is hard to pinpoint how I knew I was lesbian. In high school I had a boyfriend whom I really cared for but when it came to thinking about sex with him it was a real turn off. However, I felt extremely close to my girlfriends and just wanted to be around them. My feelings for them were really strong - like crushes. I attempted on a couple of occasions to find gay bars but I wasn't succesful so I just dropped it.
After I graduated from high school I decided to move to CA for the free college (yes it was free at the time). There were a couple colleges that I was choosing between - one was in LA and one was in SF. I asked someone who had lived in CA what the difference was between LA and SF. He mentioned SF was really gay. I had a really postive reaction to that inside - and instantly decided to move there to come out. I had soooo much fun coming out! Totally positive experience! After about six years I came out to my family and friends back in Ohio.
I found out I was bi when I was a bit older. I would constantly live through battles inside my head to make it through the next day. I finally put my life into perspective and realized my very first crush. She was my best friend at the time when I was in elementary school. I would want to constantly be around her. I would have this overwhelming desire to hold her hand and kiss her.(At the same time I had a crush on a boy too.) I never did any of those things, but it was there everyday. So once my mind check was complete I turned to my best friends and told them who I was within an instant. They all nodded in agreement and accepted me. I never opened up to family though. I was not going there with them just yet. I still need to work on that. Good luck to all! <3
