Want to incorporate vibrator...

. I ordered the butt plugs and some lube (which we almost never use since I can provide more than needed just by thinking about him taking my ass) .

Time out. Any physician or anatomist will tell you that the anus produces very little natural lubricant, so what's going on with you?

As FarmerDan notes, it's not extremely common, but there are people who do produce greater amounts of anal mucous than the average person, enough to use it as sexual lubricant, as well as those who produce it in response to arousal.

My wife produces a great deal of anal mucous. We usually only need to lube her anus to allow penetration - and often only with my precum- and I slip in easily. She gets wetter & wetter during sex.

I already met a woman who didn't need any lube for anal sex because she was naturally lubricating this way

Since I haven't encountered any actual scientific studies on the matter, but it comes up with moderate frequency in anal/AO conversations, it's possible that it's more common than we think and people just don't talk about it so it seems rare.

It's evolution: women are already evolving to adapt to anal sex...

A nice thought!
