tott666: I shaved once: never again! The itching was awful as it "stubbled".
I use a Silkepil on ass/perineum and as much of the scrotum as I can (by stretching the skin). The areas I can't use the machine on, I pluck with tweezers. I also tweeze at the pubes/dick border. I hate the "cutoff" look you usually get by shaving! I trim the pubes.
(Yes, the Silkepil hurts like hell the first few times... then you get used to it.)
And, like someone else on this thread noted, my balls hang lower when they're hairfree. Probably because the sack doesn't get sensory information from the hair?
