I shave mine every 4-6 weeks using my electric shaver. I sit on the bed against the headboard and stand a travel mirror (A-frame stylee) between my spread legs. I lie on my side and put the mirror behind my arse, in order to see what I'm doing when I shave around my hole. Afterwards, I apply hand cream and then vacuum the pubic hair off the duvet with the rechargeable hand-held vacuum cleaner. I should probably do it more often because after 6 weeks it's like a veritable forest down there!
Is NAIR a hair-removal cream? In the UK, we have Veet, formerly called Immac. This is always found in the ladies toiletries section of the supermarket, so I feel embarrassed to buy it. I'm not aware of one aimed at men. I tried my sister's Immac on my face once when I was a teenager and apart from stinging, it made the smell of burning protein (which I assume is what it's doing - burning your hair off).
