This may seem as an odd question, but I'm just curious.
Is there any need to worry about health concerns when using certain things as lubricants on a dildo? Things like KY or hand lotion are things you normally wouldn't ingest, and if they're smeared on a dildo that's being used anally I was just curious if that could have any health impacts.
For example don't use any soap! It kills very important bacterias in your bowel. But i don't know about other ingredients. That would be a good point for the Wiki.
