Is anyone worried about their fetish becoming more extreme?

I think that's just the internet. But what would you recommend instead?

More of an FYI that Betterhelp doesn't care about protecting your PII. Given that is a particularly egregious abuse of sensitive health information.

I'd look for a Cognitive behavioral therapy (CBT) therapist that is local to you and takes your insurance (if you're US based). But I have a slight preference for in-person therapy. You should shop around for a therapist that is a right fit though. Rather than go with the first one you consult with. Sometimes they are happy to just take your money and phone it in.

I hope you find a good therapist to talk with. Most of the people in here said what I would've so I'll just add that you can always send a DM if you're in need of a vent or so.

I suppose we can split hairs, but he's telling us he's sexually attracted to men, which means he leans gay/bisexual. He's concerned about that because of the rules of his culture, NOT because he himself is repulsed by the very idea of it.

Being sexually attracted to men does NOT mean he wants to be in a romantic relationship with them. But when someone says that they get off to men, I'm not sure how you conclude there is nothing homosexual about it.

Maybe I'm reading you guys wrong, but it sounds like you're implying that being gay or having gay thoughts is a negative thing, which I'd disagree with (if that's the case). I also disagree that a person "needs therapy" just because they might be gay or bisexual. Again, I think he's been VERY honest here, so if he does choose therapy and finds a good fit, that degree of honesty will help guide him to the answers he's seeking.

As for solutions about how to live freely in his culture...based on his words, that is where things get complicated.
