Shaving itself is more of a science than just another weekly routine thing. Let me give you some advice.
Wally's guide to pubic area shaving or: Shaving for the manliest of men
(1) The Lawnmower
Got really, really thick hair around your unit? Don’t be too shy to take care of it with the best tool you have. Please pay attention to the rotating blades when near the glans or other potentially important areas. Difficult-to-reach zones can be corrected with your hedge trimmer.
(2) Manual work
Let your fingernails grow a bit, then start pulling out your pubic hairs one by one. Fun thing to do when you are bored or if you need to relax. Often called the “origami for the sexually attractive man”, it is fair to say that this manner of shaving is a form of meditation. Just let it grow a bit and wait until the next rainy sunday morning.
(3) In a hurry
If you really need to get it clean and smooth but all you have is ten minutes left, try this one: have a bucket of water, a lighter and some car gas. Generously apply the car gas to your balls and shaft (pubic area, too, if needed) and inflame it with the lighter. The trick is to wait exactly until the very moment when all of your hair has been burned to ashes, but not your skin. This is when you put your manhood into the bucket of water. Please stand in a brightly lit room or outside when doing this.
(4) Stealth shaving
This is for the exhibitionist or for those rare occasions when you absolutely need to shave yet there’s a whole lot of people around you (e.g. when commuting on the train, attending a black tie dinner party in your honor etc.). Here’s the workaround: secretly use an army swiss knife (sharpen well beforehand!) under your trousers. You will have to know the position of every pubic hair by heart since you’re kind of blindfolded. Do not get caught or people will start behaving strangely towards you. You might put a suitcase on your upper legs for your convenience (if sitting) or face a wall (if standing).
(5) Perma-shave
Since this method will permanently remove all pubic hair from your body, you might want to consider this method well before going at it. Here’s how to do it: have a swiss army knife (those things are really great) or an army combat knife and start cutting off the skin of your shaft, balls and your pubic area as well. To prevent the loss of large amounts of blood, apply some band-aid after finishing. Wait up to six months for recovery.
Note: none of the methods described are meant to be serious suggestions on how to shave. Thus spoken, all attempts to file a lawsuite against me in case you might try this although the post was intended to be some sort of sick humor are pointless.
Oh, and for the record: I shave my balls and shaft every other week. The pubic area is only trimmed, albeit very shortly; almost to the point where no hair is left.
