If a woman has anal sex on a frequent basis for an extended period of time it will affect her bowel control. A larger penis will cause more of a problem because it is more likely to cause anal tears/stretching.

I don't do anal regularly but I do enjoy it on occasion...kinda like a special treat. I think gay men would be more knowledgable on the subject. As for the original question, I can't imagine it changing the size of her bm's, but what Jubei makes sense.
