Well, if a loose vagina is what I think it is, it shouldn't hurt as much, as it's small vaginas that need to be stretched during sex. Having a loose vagina, however, might dull the sensation during sex. A way to help that is to do Kegel exercises (sqeezing your pc muscles and letting them go) regularily. Kegel exercises are also useful for preventing incontinance in old age, so it's a win-win situation
