Shave the lot once a week or so. Takes 2 minutes with a trimmer. I don't bother with a razor, fuck getting razor burn down there...

So, it's not entirely gone, it's just stubble short. Close enough.

If I expect them to take care of themselves down there then I'm going to make the effort too, I prefer not to get hairs in my mouth and presume most people feel the same. I doubt any woman is going to be put off by seeing a shaven guy, a giant furball may put off those that prefer a shaven man though.
