How do I "cure" myself of bisexuality?
You can't stop being attracted to the people you're attracted to.
I, as I'm forever saying in these conversations, am mostly straight. For a man this usually means most of the people one is attracted to are women. While this is true for me, in my case it might as well mean I'm attracted to most of the women I meet.
My tastes are very wide, wildly varied, and if you look at them too closely, somewhat disturbing. Old or young, thin, curvy, or fat, busty or flat, blondes, brunettes, and redheads with straight, wavy, curly, frizzy, kinky or fro'ed hair and ivory fair, peaches-and-cream freckled, ruddy, golden, olive tan, dusky, cocoa brown, or night-black skin, from any continent or a mix of all of them, tall, medium, or short, with an oval, round, shield-shaped, or heart-shaped face, many many women, both cis and trans, a fair percentage of intersex people, and a few men turn my crank.
This includes, as you might guess, a fair number of assholes, jerks, teases, fascists, martinets, religious fanatics—fanatics of all sorts, actually.
Obviously, once I know she is anti-intellectual, or withholding, or mean to children, or virulently racist, or whatever, my attraction drops like a rock. But it's not like that minority wears signs around their necks...
My horizons are broad, but the center of my attention is probably not far from the cis-het norm. So picture me sitting in a cafe trying to work and instead wasting time on Quora, and some sweet and stunning young woman walks in. She's thin and blonde and has that radiant glow that draws the eyes of the whole room, and she moves like a dancer, swaying between the tables with a motion of her hips that promises quite a bit more worldly knowledge than the innocence of the expression on her heart-shaped face or the smile on her chipmonk cheeks and cupid's-bow lips would suggest....
As you might suspect, I would probably have a difficult time keeping my eyes off of her. My heart would likely swell with hope and anticipation, my breathing would quicken, and I would have a lot of difficulty concentrating.
Now let's whisk this whole scene to somewhere in the Deep South, where some hard-right white-supremacy group is rallying to demonstrate for the Personhood Rights of blastocysts, and fascists from all over the state are flooding into the local area.
I figure the odds are VERY high that this—to look at her—angel of beauty is in fact a demon of hate. I would rather not be attracted to her. I would rather that NO ONE were attracted to her; if she stayed childless and alone throughout her life, that would suit me just fine.
I could talk to her for a few minutes, and once I got her to say something homophobic or anti-books, I could shudder and recoil from her the way she deserves.
But life is too short. I can't divide everyone in the world into "those I'd consider dating" and "ew, gross". So instead I just say to myself, "yep, she's pretty. I'm going to Not Do Anything about that."
And then I carry on with my day, playing on Quora and trying to get back to working. When I'm done, I go home, kiss (et cetera) my girlfriend, and go on with my life.
TLDR: If you only want to date a subset of the people you're attracted to... only date those people.
