Yep. The more ordinary the clothes are, the better. I do not like leather or the spiky metal things in most BDSM porn. I don't even like cock rings or PAs.
But I do like uniforms. I like wifebeater shirts (a lot). I like boxers. I like baseball caps. I like jeans. I like rock-hard dicks sticking out of jeans. It's a plus if they do normal everyday things while their dicks are out. Like walking around or talking or joking around.
It's that clash between the ordinary and the erotic that makes it hot for me. Same reason why I find masculine guys getting fucked very hot. Or a bearded guy with cum on his beard.
And yes, one of my biggest pet peeves is in uniform fetish. When the soldier/cowboy/businessman/blue-collar worker/etc. completely remove their clothes before they even start foreplay.
What's the point in dressing up if you're only going to take them all off in the first minute?
It's a bit hard to find porn like this though. I can't even remember one where they're fucking. Most I've found are in solo or short badly-shot amateur clips. One of my favorites for solo is TJenner on Pornhub, who also has a very nice voice.
I'm not that big of a fan of Men At Play. Their men are usually too perfectly coiffed and manicured, which is a turn off for me.
