Ok. Wow. This one will start many fires. Here is what I believe, this is my own personal view, take it or leave it.
I am gay. I just am. It is in my blood. I was gay before I know what that meant. I was very young, 5 or 6, I knew that girls were interesting and that boys were too. It wasn't just a "phase".
As you are a woman, putting aside any lesbian tendencies.... when you meet a man that you find attractive. Is it just that you want to jump his bones? Or do you want to know how he feels, what stuff does he like, what's beautiful, what's ugly; do you want to know his soul? I bet you do?
That is how I FEEL about men. It's not just sex. My heart, not just my mind, gets involved. I have had the same feelings for men, that straight women do, I'm a counselor of sorts, people tell me their lives all the time, I have heard all the drama. So I know that they way I feel cannot be excluded.
And I'm not a sex fiend, I actually don't like anal sex, there are gay men out there who don't like butt sex! I love to do other things, wonderful things. But I don't randomly attack guys on the street because they make me horny.
When I see a guy that's good looking, in the way I really like, I'll look for signs that he might be gay too...if it's not obvious. If it turns out that he's not gay...I'll let him be and continue on with my life. I will not try to convert him or try to convince him that some religious dogma has said that heterosexuality is wrong. That would be silly!
Even if he was gay, there's no guarantee that he'll want to be with me? I have well meaning straight friends who try to set me up with their gay friends all the time, but they don't take into account personality or emotion, they just assume that because we're both gay, we'll fit together.
Randomly pick a man and a woman together in a room. So many things may happen, but unless several impossible things suddenly align, they're not going to just attack each other.
I am gay. I have a heart, just like you. I can love, just like you. If you want to deny yourself love, even if it comes from another woman, it is your choice to ignore, but the feelings will always be there. And I know you know this, deep in your heart and soul, you still feel love for women and not just men.
You can make a mental choice to be hetero, but the homo part cannot be changed. It is who you are.
I wish for you that you find a great lover, but let them be what they are, be they male or female, I hope in that moment, when you find them, that you will also let yourself be what you are. :)
