Finally, a topic I know something about { well, the oral techniques for a good BJ is another}. I submit that the best, easiest, safest and quickest way to shave the brown starfish is ........ in a steam room.
Yup, now calm down, I only do that when the steam room is empty. Lie down on a towel, legs up; one hand on a butt cheek, the other with the Mach 3, and do one side. Switch hands, do the other side. It can be completely finished in less than 15 seconds. { I know, I timed it }. Clean, no shave cream, no mess; wipe the blades on the towel and rinse with water. Good as gold. The steam sets up the hairs - all over the body - and nothing else needed except a good set of blades.
The advantages of have clean shaven pucker puss is: easy clean up after a bowel voiding {learned that from Howard Stern}, and makes salad tossing much more safe and enjoyable - for all those involved.
As somewhat of an expert of this type of shaving, I would be happy to offer my services to Wulfgar sometime. A little massage of the area, some professional shaving, a little prostate massage to 'finish' things off....better than a massage at Georgette Klingers!
