I noticed I wasn't really into men at a pretty young age, around 13 or so, but I didn't realize I was looking at women sexually until I was around 17 or 18. I think I simply suppressed it because being bi was just a trendy thing, and I didn't want to be trendy. I also really wasn't aware of my sexuality for the most part. I just knew I wasn't really attracted to men, I thought women were pretty, and I had a pretty high sex drive, but no one I really wanted to enjoy it with. With all those things together it took me quite a long time to figure my shit out.
I would have crushes on girls as a child butnever made much of it since I knew I liked boys I figured it was normal and I was straight. I didn't know what a bisexual was. I started realizing in high school I was about 15, 16. I would always catch myself looking at girls and would still have small crushes. I figured I must be bi.
I first REALIZED when I was maybe 14, but when I told my friends about it, they were less than understanding (as children/teenagers can often be). I was ridiculed enough about it that I tried to "take it back" and forget about it because friendships were being lost over it, because some thought I was "disgusting" -- I lived in a very conservative town at the time, sadly. And when you're that age, your friends are everything to you. It wasn't until maybe last year that I sat down and re-examined those feelings again and realized that I ought to be open and honest about who I am.
I think I first identified myself as "bi" when I was 12 or 13. I remember writing in my journal "I am bisexual." Over and over again so it'd seem real to me. Then "straight" for awhile. The "lesbian." Now "bi" again. I don't really feel a need to label myself anymore, but I'm pretty comfortable with "bi."
I remember being alone in our office at home, typing in "boobs.com" when I was young, maybe around 8 or 9? I was curious haha. For some reason my sexuality has been quite present since a very young age. While my friend's barbies were out shopping at the mall, mine were 69ing Ken in the dollhouse. Both men and women have been sexually appealing to me for quite some time, but it wasn't until last year that I admitted to myself that I'm bi. I'd like to think that it means that I have a whole other world to share myself with
