I think guys get a bit wet when you are stimulating their ass (like when you go to the bathroom, that makes it easier for something to come out lol) but i'm not like 100% sure.
also they are wet from lubricants
and also - there is no biological difference between bodies of gays and straight guys ... again lol

well men commonly discharge seminal fluid from seminal vesicles and prostate gland for lubrication during sex, usually released by arousal stages. however, self lubing ass holes. No that's just a yaoi thing. Anal sex requires preparation with oils or lotion for men and women lol. Going in raw without even stretching it? Major ouch in real life. However it's often omitted or ignored in porn, or in yaoi, ukes with their self lubricating butts my goodness.

when i posted my comment i meant artificial lubricants, just to be on the safe side. haha
and i've noticed a lot of times they are talking about dicks. precum.

what? which is your comment? but yeah, men release seminal fluid similarly to how women release vaginal discharge for lubrication during sex. In females, it's from the vaginal walls as well as vaginal mucus made of carbohydrates, amino acids and proteins.
Still no on the butts though. If your comment was referring to when you use the bathroom, that particular movement is due to smooth muscle contraction, "lubrication" would be dependent on the fluidity of excrements as large intestines is the region to absorb water. My goodness if there were any "extra lubrication" it would be blood if you experience constipation which can be very bad if commonly experienced as it's not suppose to be there and can cause abdominal pain from internal damage.

Gay guys are the same as any other guys.
I believe he was reffering to pre-cum that may have dripped down or smth. There is no other wetnes down there no matter how much you'd stimulate guys ass :)
BUT! You know how it is when it comes to smut. If the author wants him to produce extra fluids like a woman, he will.
It's just like with girls squirting milk when orgasming. Does it happen? No, unless you're in late stages of pregnancy or right after birth. Still some artists draw whatever they want.
Oh and there is also omegaverse (not real antasy universe). I suppose those guys can get wet since they also can give birth?

I always find that line cringy XD
Guys I have a question but pls dont judge me. In some yaoi manga seme said to uke "look at you, you are so wet" something like that. I know guys cant get wet. Gays can? I didnt understand
