I Think I Am, I Feel I Am, I Witness I Am, But I Still Doubt It

Okay, so I am a 21 year young female and currently in a relationship. I have realized since I was in 5, or 6th grade that I have always noticed girls and thought of them as "cute", which was a very few words I know now to say, "hot". I always like boys though, the big hype growing up with this boy is cute, and that boy would look cute with you. I always had these major crushes with boys, but inside, I always secretly gazed at my girlfriends (female friends) and wondered about their lips, look at the shape of them, listen to their voices and how they enunciated words. As well as their, I'm shy at even typing this on an online community, but as well as their breasts, for I envied those big, perky breasts that I felt I did not have full capacity of. Yes, I do have self-esteem issues if you have yet to notice, on a side note to you, the reader, thank you for taking your time to read my story because I have no way I can open to my girlfriends aside from guys and my boyfriend. I digress, well, I'm in college now and have had serious highs in women and lows in women. As in highs, wanting to experiment, which my boyfriend new of and wanted to be present if I did, but would only watch which I grew selfish b/c I wanted to experiment by myself not w/ him around, which he later said would be cheating cause I wasn't there, but I didn't want him ************ to another girl... Lows because I am in a serious relationship with him, about to be 6 years with him, and still not sure what i think of it. The number one thing that is evidence that I still have feelings for my sex (female) or, well, still have it stirring in there, was this incident I had in Vegas with my friends.
  Well, some friends and I went about vegas for the first time together and one of my girlfriends was really, really drunk. She was a light weight. One of our friends was taking care of her. We walked around trying to sober her up, but she just wouldn't. Well, there was a point where She was holding on to a friend for balance and I was pointing at something across from us, which so happened to be near her face, and she just bit my finger. It wasn't like an, "OUCH MY ******* FINGER," kind of bite, it was like, " wtf?"
  At that same moment as she had bitten my finger and laughed like a drunk ***, I wasn't thinking about my finger being bitten, I was looking at her for a moment with an odd warm feeling in my chest stirring inside with other feelings and what I really felt was a soft pair of moist lips on my finger and teeth against my finger, but the warm moist lips and its feathery softness was what I remembered most, which caused whatever this warm feeling, to stir and just, well, I was stunned that I had this feeling period!
  I couldn't help but feel, well, comfortable, but uncomfortable. I knew what I felt, but I couldn't talk about it with friends that were there, I was yet comfortable with them. ..

  Well, there is more to it, and I do not want to go on and on, that is my main suuuper main reason I still believe, well, and uneasy, that I am bicurious. I am not saying its a bad thing that I do feel that way, but, the fact that I am not sure, somewhat, and that I am in a serious relationship and not wanting him to envision another woman other than me.... I don't know and I am not stressing about it as much now b/c, I guess, I just stopped trying to get this experience with someone who is w/ females, and just let it be b/c I just don't know i I am, or am capable of being it.. well, i don't know.. I'm scared I guess, not of being it. More like, hurting my mans feelings... I don't know.. well, I'm gonna stop here, I write too much.

  To those who stuck around to read this, thank you for your time and please, if you just want to rant about how stupid this is to you and don't have any positive feedback just negative, just keep it to yourself. I can take constructive criticism, but not stupid, demoralizing, discriminating comments. They are not wanted here, please and thank you.
