What should men really do, shave or trim or wax etc. If I trim how short? If I shave how? If I wax what should I use? Can someone pleeeeese help me!

Shave WHAT ? Trim WHAT ? Wax WHAT ?
Shave your beard / mustache ? Your armpits ? Your groin ? Your belly ? Your arms / legs ? "Bikini" bottom wax ?

:D

All of the above mainly the groin

I would guess to say that most mean on the groin don't do anything,
Some men trim and shave.
Wax? Hurts just thinking about that.
