^^^ that's the explanation, indeed. And everything else like shaking hands is done with the right hand. You should never offer them something with your left hand.
I knew it. I knew something to this effect must have existed. Think it might sort of answer the OP's question. https://www.youtube.com/watch?v=X-9uxdrmMl4
Seriously, where guys just do toilet paper and go, I think chicks keep cleaning wipes next to their toilets.
Are they biodegradable though? Because if they're not, and if they're flushed down the toilet, then that wouldn't be good!
People carry hand sanitizer around, freak out if someone double dips a chip...but they will lick assholes. Makes no sense to me. But yes, I believe most women (unless you own a bidet) will use wipes after a poo.
I don't mind doing the old lickeroo on my wife, but I'm not always in the giving mood, and shes not always in the receiving mood. She does not return the favor and I don't blame her, its way too hairy down there, it does not cleaned well no matter how many sheets of TP I use. That being said, it does not have to be spotless to be presented in doggy style, remnant flecks don't exactly stink to high heaven or advertise themselves with neon signs. You'd have to be looking pretty hard to notice, and that doesn't work well in the dark.
