Hi Skitty!
I know exactly how you feel. The only thing that works for myself is to look deep inside, and I usually find the answer waiting for me there - just quiet that little voice of your ego, that keeps saying "I want to be like this", "I want to be like that" or "I can't be like that, please, anything but that". Whatever is left, whatever you truly feel in your gut, that's who you are. (That doesn't mean that you have to _fully_ give into _every_ temptation without thinking of the consequences - not even straight people do that.)
Being totally honest with you - right now I don't believe in _true_ bisexuality. You're either straight or gay, whatever you do with it is just a statistic. I don't have much experience, but the "bisexual" people that I've met so far have simply been gays in denial or trying to live another life. True bisexuality might exist, I don't know, I just haven't met anyone like that, whom I'd believe.
Personally, I think I did enjoy heterosexual sex - you still get to share an intimate moment with someone, you still get to cum
But what I've realised now is that _true_ attraction and _true_ lust for me exists only for men. So I believe I'm gay. I still might have sex with women, but I know it's a different thing. Would I enjoy it? Most probably yes. Am I bisexual? Statistically, yes. By _true_ nature? I don't think so.
Now for me that was hard to accept - because of the culture that I grew up in. That might be the case for you too. Here's where I found courage to face it:

imdb.com/name/nm0000015
Recognise them? Two of the greatest and most iconic actors ever, both queer as hell. And both were _loved_ by the ladies, and both took advantage of that, in one way or another. Brando even had a family, and nine kids, as far I know. A more recent example:
imdb.com/name/nm0362766
Someone who has embraced his homosexuality, been married, has a kid, seems to be a great person and a loving father. And an awesome actor too.
What I took from these guys for myself was: don't be afraid of who you are. Embrace it. Understand it. But don't let just one thing fully define you. Just be aware of what you really feel, not just sexually, but in every important aspect of your life. And make choices based on that. Not based on society's prejudice - not the one that says that you can't be gay nor the one that says what you must be like if you are gay. Understand that you are a real, living, feeling human being and your basic right is to strive for a happy life.
If you feel like talking more or if you just need someone to listen, send me a private message.
