Hope you well , i need an advice from the dr me & my wife we started anal sex & we used different types of lube , but my wife she's feeling more pain when starting intercourse. what can we use to prevent that pain?

Not designed for sex: There are billions of bacteria coming down into the anal-rectal area all day long... such as E. coli, Klebsiella, and all sorts of other species. Scientists say there are more bacteria in the intestinal tract than there are human cells in our entire body (we are outnumbered). To stay safe, an anus should be reserved for the activity it was designed for, just pooping.
