baby, as a guy who loves it in the ass, i CAN tell you it doesn't get wet when insertion happens. there's a reason you need lube. like someone else here said, your intestines only create a kind of mucous when your body is sick and sometimes you even need to eat more oils to help your large intestine lubricate itself so you won't get constipated (doctors recommend vegetal oil in this case). now your anal canal, that's where the party happens, won't really get wet, especially if friction is happening.
2025 and yaoi authors still don't understand assholes don't get wet?
