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 :
total smoothie past 12 + years , I use a Norelco body groomer takes about ten minutes neck to toes . there are so many different body shavers / groomers out there now days I don't know who would use a razor. as you shave your hair over years it doesn't grow back as fast and I can go a week with some touch up .
Without having ever had the term sink into my consciousness in my recollection, I have been following the "bikini season" ethos for many years. I guess it's because I only get to the beach, whether nude or textile, in summer and don't get to go in winter. Last (southern hemisphere) winter was no different but the hair went soon after thoughts of returning sun and warmth outside entered my mind.
