Not very often, my hair is very spikey, so I let them grow for some time. So once a month probably for me.

Touching the shaved balls gives an amazing feeling though.

I use Philips BodyGroomer - http://www.amazon.co.uk/Philips-BG105-10-Bodygroom-Protector/dp/B00T7M7VA4

Are you aware of smegma - that white smelly stuff naturally forming under foreskin of uncut penises?
How fast yours is produced?
I have to clean it in the mornings and in the evenings, otherwise it's getting too much of it and it can get smelly. So I really have problems when going somewhere where there might not be any shower or simple facilitites for personal hygiene. Usually there's no spontaneous sex for me…
Plus when I come back home and my boyfriend is really horny and wishes to have sex straight away by the front door, for example, I'm always asking him to wait till I shower first... which is not very sexy and leaves him a bit upset.
I heard that an aeration ring can help it to produce less smegma...
What do you usually do if you have the same issue?
