Your premise is off... you cannot "categorize" bisexuals any more than you can homosexuals!
In this forum alone, you likely have men like me, who:
love smooth men, but not hairy men
love thin, lithe men and women
love intelligent, sarcastic, whimsical men and women
I could go on and on - deep into a diatribe into all the different kinds of things men like (or do not like) sexually...
But here's what I've taught my sons:
Every man is "wired" a little differently - and there is no one, single, "right" way -- although there are many "wrong" ways (pedophilia, rape, public (unwanted) exposure - and others - are indeed "wrong" by our societal norms)
As a man, you owe it to yourself to explore "how you're wired" - and
that means experimentation.
Fortunately, you have a near-flawless indicator built-in:
If your penis gets hard, stays hard, and you have an amazing orgasm - it's probably something you're wired for....
But, if you have to struggle to stay hard, or cannot reach an orgasm (yes, men CAN fake an orgasm!), then you're probably NOT "wired" for that...
And, if either of these experiences are "repeatable" - then you're getting a good idea about what makes you tick!
As you learn to "map" your own sexuality, also learn to
accept it - because you don't get to
choose it, it's just who you are... the earlier you accept this, the happier you will be (at least in your sex-life!)
Remember though - your "sex map" is not a static, unchanging thing... it can (and likely will) change over time. (For example, at 20 you probably won't find 50 y/o men or women sexually attractive, but 30 years later, at 50, you likely will!)
Finally:
don't overthink it (or over-apply your mapping): if you can't get hard with her, it doesn't mean you're gay - only that you're not into
her!
As an aside to readers here: I strongly believe in experimentation - I've known men who thought they were 100% straight - until they had their first m/m encounter! I've also known men who thought they were 100% gay, until they had a sexual encounter with a woman!
Even in the realm of most "kink" - my belief is "don't knock it 'til you've tried it!"
