One of the nice things about being my age is that I do have hair options - at least the hair that's growing in the area this question is mostly concerning. I like to mix it up downstairs, leaving a healthy fur there during the colder part of the year, keeping it closely shorn during the warmth of spring & summer, though the rules are all up to me, at least at this point. I've heard that many of us begin to lose the genital hair later on, not something I'm looking forward to if I end up being one of those people. As a fun little treat for myself during those long winter months, I will sometimes smooth it down completely while still leaving a tidied-up patch up front for easy suds production.
It's a razor for me, a Braun electric unit with a head I keep dedicated to my dicktator and his minions, and it does go all the way 'round the Solar System (if you know what I mean), settling the Hair Wars somewhere dark and scary all the way out to near Neptune's moons :
