cleaning butthole before anal

Am I the only one that uses this? I have a lot of gay guy friends and they all use this. I love that it cleans me really good. I dump all the liquid that comes with it into the sink and replace it with warm water and squirt it up my butt while I'm hovering over the toilet. I have to make sure I'm extra clean because my man loves eating my ass and sticking his thumb in my ass while he's hitting it from the back (it's the best).
