Italians have lots of phrases relating to the amount of "milk" accumulating in their balls, indicating frustration (about non-sexual things, too!).
Yorkie - I love "wizard's sleeve" as an expression
OK - I'll give a few more British terms, these being colloquial or derogatory expressions for gay men:
Uphill-gardener
Shirt-lifter
Beaver-leaver/Vagina decliner
Starfish trooper/Arstronaut
(as in Brazil) Pillow-biter
Crafty butcher (hides his meat round the back!)
[please note - I'm just reporting, not putting-down anyone!]
