I use a
Norelco BodyGroom from Phillips for my body and it has been great.
I never trim to 0mm and always leave very little 'more-than-stubble'.
However, I do use
Prospectors Beard Oil on those hair once I am out of shower and that prevent those hair from being a cheese grater during sex.
The best way to go about using the beard oil is putting it on you face first so most of it gone and using the residual amount on your hands to get your hair down south. If you go for pubes with a fresh glug of bread oil on hand, it'll end up ruining your underwear overtime.
It is bonus that your junk smell immaculate AF! 'I've had girls come up behind me at Starbucks be, "Damn! is that your balls?"
