Questioning

As cliche as this following story may be, I am working to understand my sexuality.

When I was 15 I went on a vacation with my (very straight) bestfriend and her family. At one point in our trip she held my hand as a friendly gesture, and to my surprise my stomach dropped to my knees. I had never had that happen before with a girl. So the rest of the trip I did a lot of thinking and experimenting trying to figure out what had happened. To my surprise it ended up being more than a one-time problem. Everytime we would hold hands, something we had done many times before, i would get butterflies. I found myself putting my hand out hoping she would take it, being disappointed when she didn't.

I didn't put much more thought into it for awgile. A couple months later I was speaking with another close friend of mine, mentioning that I was less sure about my sexuality than I had been in the past. I told her about what had happened when I was on vacation and it got me thinking about it again. Not long after I realized that i was falling in love with her. When she began dating a guy, I was completely heartbroken despite the fact that I could never see myself with her. I eventually found the courage to tell her and she was very accepting, but as I knew she was as straight as an arrow. This lasted for months. During that time I started dating a guy, which distracted me from my feelings for awhile. I found myself, towards the end of our relationship, only wanting sexual things, I was bored by just hanging out with him, and I have no way to know if it was because we were not a good match or if its because he's male. We ended up breaking up in about 5 months when I realized my feelings were back for my bestfriend.

Fast forward over a year later, my feelings for her are still around, but they are no longer much of an issue. The problem now is that I can't stop thinking about my orientation. I've often been told that I will figure it out in time, but I am the type who loves labels, I like things to be simplified in my mind.
ave been with men and never anything with women. Anyone who has any similar stories or any thoughts please help me out, I have been thinking about this for quite some time. I am quite fortunate to be in a community where this is widely accepted, I can't imagine how hard it can be for others to figure this out by themselves or in secret. I thank anyone who read all the way through this.
