How to have anal sex without a mess?

Enemas the night before -- about three bags.. Plain water. You need to hold it in as best you can. Not always easy. Don't put the enema tube very far inside.. less than 1/2", use a lubricant like coconut oil or olive oil. You don't want to tear yourself.

She should go to the bathroom several hours before and then wash thoroughly before trying it. Some will take an enema a few hours before, but it is not necessary in most cases.

Have the girl take a wash cloth and soap and really clean down there before you have sex. I make all my girls do that because I like to toss salad before I get to humping. Besides that, use a condom, and plenty of lube, and go to town on that assss.

there is no way - that hole is exit only

get an enema
