No Hair!

I need some ideas on how to nicely tell my husband that he needs to shave his downstairs. I like hair but it's been a while since I've seen him shaved down there. my husband gets embarrassed when I bring stuff like this up to him. I always try to be nice about it and I try to always maintain mine so that he'd never have to say anything to me. It sucks because I love to play with his balls and even lick them and everything but It really kills the mood when they're hairy.
