Ladies, would you be willing to let your pubic hair grow if your boyfriend/husband asked you to?
What do you mean by 'grow out'?
Full bush? No way.
It's not just about *looks* (which, I think, most men assume - they assume it's all done for looks AND it's all done for them). But there's also routine maintenance, like all other body hair. For some it's hygiene meant to keep down odors and unsavory things like 'pubis cling due to vaginal / menstrual secretions' . . . being female, I find these things to be absolutely disgusting - yet a fact of life if you grow any little bit of it too long (even with showering once or twice a day). Tolerate THAT just because he might want it longer? Nope.
Further, I like the sensation of being trimmed during sex - and when both people are ungroomed there's a really icky 'sound' that two full wet bushes make. Seriously - it's laughable and silly and I couldn't stand that, either.
I did in my twenties when David and a photographer friend of his wanted me to do a photo-shoot with a full bush.
