I worked in a small town in a job where I employed HS/collage age kids. They would tell me stories....one was about a girl at their school who was well know to be an anal queen. She went on to be a cheerleader at IU. Until she was asked to leave the team. It seems when certain forces were applied to her body, as does happen during the course of a cheer, she would fill her panties. Not something you want to happen in front of 10k screaming fans.

I do not know if she was still engaging in anal sex, but I would guess yes. So having a foreign object stuck up your ass on a regular bases does have its consequences.
