Thread: Prolapse Concerns Due To Anal Sex?

There can be "stretching" issues of the sphincter muscle. This is the muscle that must relax when having a bowel movement. When this stretches (I've seen it in the hospital) then people have resorted to using tampons etc to stem the leakage that can occurr. This stretching is probably from foreign objects being inserted as an average sized penis is probably no thicker than a large bowel movement. Anal sex can be fairly safe and if you're using lots of lube and it's not rough sex then you should be ok. There might be some advantage to having her perform exercises that strengthen the sphincter (almost like kegal exercises in which you tighten and relax the vaginal muscles).
