Seriously, it’s a lot more sanitary for everyone involved. You’re gonna be naked and your butthole might run against something or other, so make sure you’re not getting your shit on anything. Plus, you might not think it smells, but your partner might think otherwise. They might just be too polite to say anything. Use baby wipes or soapy water.

For those of you wondering: Yes, there are some grown adult humans with fully developed brains who need to be told this. Even if you’re not involving your anus in the sex, it pays off to keep it clean. It’s one less thing to worry about for everyone.

No, it’s not “gay” (and what would be wrong with it if it was?) or “demeaning”, it’s what you’re supposed to do. You’re not “less manly” or any other “negative” trait you might perceive it to be, you’re practicing basic and necessary hygiene.
