To add to the superpower threads.
You can change anyone’s sexual orientation, not limited to regular variations, you could make someone only attracted to cats or grass.
Would you use it and how?
Not bad enough for enemies, not nice enough for friends. I’ll pass.
Every Republican becomes gay or transgendered. They can choose to turn back, they tell me.
This. Although I once had a friend who regretted not being gay. I guess if I had that superpower I might have offered to use it on him.
This is one I’d just open a storefront for. Plenty of people would probably pay for “adjustment” to fit in, either to society or to their own beliefs. Ethical but unhappy pedophiles, conservative religious folks with “bad thoughts”, etc.
Trans isn’t a sexual orientation.
Sure, I’d make all sexually predatory people asexual.
So it sounds like you’re talking not just about sexual orientation (straight/gay/bi etc.), but interests/fetishes. And if that’s the case, then I’d seek out people who seek to suppress the sexual freedom of others, and give them one or more of the least socially acceptable (but harmless-to-others) fetishes. Rick Santorum, for example, might become a big fan of, oh, maybe pony play.
Do I change them back if they become more supportive of sexual freedom? Nope.
Heck yes, I’d use it. Me and Sasquatch could go into business together.
Then I would advertise my services in California and dare them to do their worst.

Every rapist/sexual abuser becomes asexual (or attracted to stuffed animals or something if asexual is not allowed). Every adult sexually attracted to children loses this attraction and becomes attracted to adults only (unless they’ve actually abused children, in which they become asexual or stuffed animal lovers, per the first rule). Every person who has advocated (and hasn’t repudiated past bigoted views) mistreatment of people (jailing, stoning, segregating, etc.) for their sexual orientation or gender identity becomes gay (no outs here for “gay people are fine as long as they don’t do gay sex”). Every person who sincerely wishes they were a different sexual orientation gets their wish (unless it conflicts with the above rules, the first being the ‘highest’).
I don’t think I’d use that superpower. Maybe if a man was staring at me so much that I felt uncomfortable, I’d make him attracted to men in hopes that he’d stop creeping me out. Other than that, I wouldn’t use the superpower.
I would use it to change people who have a criminal/harmful sexual focus (pedophiles, actual sadists, etc.) and people who are distressed by their current orientation (devout Christians who believe being gay will subject them to eternal damnation, as an example). I would not use it to change a child’s orientation to make parents happy (you’re kid is gay and you’re upset? Too bad - if they kid is OK with being gay you’ll just have to deal), or force anyone else to change against their will (so those pedophiles can choose jail or change).
I suspect I actually would seldom use this power.
Unless I can change the sexual orientation of people and also make it so they have sex in front of me, it’s of no use to me.
I’m not saying the above is a wholly ethical way of using the power, but it’s pointless of me to go “Man it’d be hot to watch those two girls go at it!” and change their orientation just to have them go off and pork other people.
I’d make all the hot women attracted to me? 
The most useful application would be to treat people who have dangerous, destructive or otherwise clearly unhealthy sexual urges (pedophilia being an obvious one). One could have a positive effect both on individuals and on society this way.
That said, the urge to make Vladimir Putin and Ramzan Kadyrov develop a strong sexual attraction to each other would be sorely tempting.
I’d make Mike Pence the horniest gay in history.
“Look! It’s AmbiSexual Man!”
“You mean Ambisexual Woman!”
“It’s The Ambisexual!”
I’m sure I could make a pretty penny changing people’s orientations, adding or removing fetishes, and charging the state to remove the urges of convicted pedophiles/etc. Assuming there’s no limit to how many times I could use the power on a single person, I’m sure I’d eventually use it on myself, just out of curiosity.
How close do I have to be and how specific can I get with it? Could I, for example, make the leader of ISIS attracted only to enraged bulls, frenzied sharks, and starving piranhas? Can I only change who/what a person is attracted to, or can I also change the intensity of the attraction? I’m sure plenty of people would also pay to increase or decrease their sex-drives.
This was a villain in a comic me & my brother did very little work on many moons ago: Vice-versex, he blackmailed rich homophobes and caused a moral and sexy dilemma for the heroes.
You can be very specific & change sex drive but have to be able to see the target (on TV doesn’t count)
My wife often complains about sore feet and during all the times I’ve spent rubbing her feet I often wished I had a foot fetish so at least I’d be enjoying myself. So that would be one use for the superpower.
But yeah, there are lots of people who have dangerous, distressing, or unethical sexual desires. Being able to remove those would be helpful.
I wouldn’t use it to turn Rick Santorum gay, that would be unethical. But the existence of my superpower would be strong empirical evidence that sexual orientations aren’t a choice. If I can mind-zap a pedophile into asexuality, or successfully turn a self-loathing gay person straight when conventional therapy won’t work, it would be strong evidence for the “born this way” theory. Pray away the gay doesn’t work, but Professor Pheromone’s invasive treatments do work.
This power is straight-up mind rape if it is used against an unconsenting person. For violent sexual offenders I could justify using my powers without their consent, just like Batman uses his power of punching people in the face against violent sexual offenders without their consent. But against mere assholes and dipshits? Nope.
