All this banter is very fun and enjoyable, but I feel the need to give a couple warnings here about safety, hygiene and preventing exposure to blood-borne pathogens.
First of all, you must use a fresh, out of the cartridge-holder blade each time you denude the nutbag. Or, reserve a special razor for this purpose.
Reason: Hair shafts on the face and genitals are of different shapes. Your beard wears down the ultra-keen edge on the blade, making it more likely to cut sensitive flesh if you use it down below!
2. Never, never, never use a razor to shave the boys that a partner has used to shave her legs/underarms/back.
Reason: Blood-borne pathogens can often survive on the blade. Some diseases, including hepatitis can be transmitted via sharing a razor blade. It's a lot like sharing a needle.
3. Don't rush. I'm very steady-handed when I shave the danglers, but even so I proceed with caution.
4. Minor nicks/cuts should be treated as any other minor first aid emergency. Clean the cut and use an antibiotic ointment. A styptic pencil is probably not good enough prophylaxis.
5. Cleanliness of tools and environment is paramount. Aftercare is important.
If you've read my contributions to this forum over the last few years, you'll figure out that I'm maybe a little overly concerned with safety. But hey... you've only got one blue-veined fuzz-baggie...take care of it!
Cheers!

Now, start shaving, bitches!
