I have the equivalent for the ladies summer skirts/bare legs problem.
When in the barbers, I was idly reading 'Mens Health' which had a review of grooming products.
One product was formulated to deal with the problem of (let's be clinical here) the testicles adhering to one's thighs. A problem that up till then I did not know existed.
They even had a name for it - sorry I can't remember what it was.
The other interesting product was a willy brush called the 'Pipecleaner'.
