I know I came across this post pretty late, but I just had to read it and reply to it. I completely relate to this. Even for just being 17, nearly 18, I deal with most, if not all of the things above; the way I feel towards each sex, hearing how that, because I'm Bisexual, I'll eventually turn full-on gay, etc. Which, to be honest, I have to disagree with. I love women too much to be gay. And, likewise, I enjoy guys too much to be straight. I'm snug in the middle of it all. And what's funny, it's kind of exciting, because I don't know which one I will end up spending the rest of my life with. I'd find it ignorant of myself to say that I should choose just one to like over the other, although, like I stated before, that's pretty much impossible. And a major misconception that really urkes me, is the thought that just because I'm Bi, I'm completely promiscuous, and cannot keep a relationship with just one person, and instead resort to sleeping around with many members of each sex, consistently going back-and-forth, and so on. Why is it so hard to believe that I'm capable of this, just as are many other Bisexuals?
I remember the first person I ever fell in love with was a girl who I'd known since the second grade. She was my first in everything. I loved her so much, that I couldn't even define it. But, eventually, after a major rift in our relationship, we separated. It was hard, hella' hard. After her, I continued dating girls, had a couple serious relationships, but not so serious as the one I had before. Then, further down the road, I came across something that I hadn't really ever experienced before. I began falling for a guy in the same way I did her. Now, don't get me wrong or anything, I new beforehand that I had an attraction to guys, but I never really acted upon it up until this point, really. But what I did realize, was that I was just as capable of loving a guy as I was a gal. That was an amazing moment for me.
Now, a while later, after being single for a while, I'm still waiting for that person to spend the rest of my life with, whether it's a guy or girl. And I fully intend on loving them with all my heart and with everything I've got. I'm still young, so only time will tell. Besides, I like surprises.
And I can really relate to your descriptions of sexual responses to each gender. It's much the same way for me. Kind of funny, really.
Anyway, I realize I've just written a bit of a novel, but I thought I'd just share this point here. Oh! And by the way, I plan of reading your "Crosscurrents" story. I feel, from reading about it and such, that I may relate to it in a few ways. And I just wanted to thank you for posting it, and this blog.
