Keep that loose little bootyhole cool. If it overheats nobody will want to put their fingers in it anymore.

We evolved as a naked mammal, then we invented clothing which interferes with the natural evaporation process. Option B is to bathe or be European and use a bidet.
Many parts of Europe use the bidet for just this reason. A clean bum is a happy bum (and doesn't stink... probably)

then you must know how good it feels when the wind blows on a hot day

And it actually evaporates instead of sitting there feeding bacteria
Edit: At least I think that's what the point was

Likely similar to the reasons why dogs sniff each others' butts upon introduction. (Goes with @spookybm's response)
Being the dankest, sweatiest part of a body close to the genitals means it's probably the easiest place to find various identifying scents and hormones for animals with strong senses of smell.
But since our noses aren't that strong, it just smells like swamp-ass.
Would also be an unfortunately disgusting explanation for fetishes involving asses.
Science!

Makes sense. Seems like a vestigial part of our bodies, but since our scent over time has lessened, the advantages remain questionable.

Indeed, at this point it's likely one of those things that evolution has backburner'd for the time being, since it doesn't have as much of a noticeable impact on continuation of the species anymore. Not needed enough to improve it, not detrimental enough to remove it.

Our scent has lessened over time? You've never sat on a commuter bus next to a nigger apparently.
Oh, I see, our (humans) scent has decreased. Sub-humans still stink like the filthy animals they are.

To keep the asshole from chafing. Try pinching out a log with a raw, dry, chapped asshole.

But that's what rectum mucus is for, right?
[–] CharlieSheensAIDS 0 points 1 point 1 point (+1|-0) ago
Rectum mucous is what takes care of the internal part of the rectum pucker, the sweat glands moisturize the outer part of the butthole pucker. Rectum mucous doesn't leak out enough to the point that it takes care of the internal rectal cavity as well as the external butthole and buttcrack.

Evolutionary advantage is a misnomer here. Not everything that's 'evolved' is necessarily an advantage. As long as the characteristic, in this case sweaty butt, isn't such a disadvantage that it results in the species being eaten by dinosaurs faster than it can reproduce. There are lots of things about the body that are inconvenient but not fatally so.

There was no inherent evolutionary disadvantage to them so they never went away. Asians don't get swamp ass apperantly.
