I am a girl that has never had a haircut or shaven her body why should I ever?

Whatever makes you happy. Your hair must be very long.

Because razor blades are on special right now.

U shouldn't if u don't want to it's only a personal choice and no one can make that choice for u except u!

You don't have to shave or get a haircut if you don't want to. There are guys out there who are cool with that. But the United States society may frown upon it because it's not "normal."
