don't forget, it's also for when you don't feel quite right... and after sex... come to think of it, it might be better to douche before sex. and then again after sex. and then rephresh.
most women know not to douche too often, as it can cause the same messed up toxic shock that tampons do; instead of sucking you dry it changes your pH too much and can cause serious problems.
speaking of douche, where's that guy billy mays? talk about a douche... next thing you know he'll be doing those commercials in that obnoxious voice of his, "Women, have you ever had that 'just not right' feeling? repHresh!"
