I know my master uses hair removal cream, then electric shaves away any strays. (Didn't see anyone mention hair removal creams as an option, so shared his method. Also reduces risk of razorburn, as razor plays such a minimal role then.)
My personal preference is manscaped, groomed, shaved, trimmed, any care given.
I won't show any sign if no grooming is done, it isn't necessary, but might have to stop a few times to pick hair out of the mouth which can kill a mood depending how long it takes.
But am sure there's a spontaneous smile of appreciation when hair has been removed for my enjoyment. And makes it easier access to play with testies.
I like the comment that points out, how do you like her groomed as an answer to if you should or not. By Duoman in 2023.
