bater's block 

like writer's block, except a condition where a person is unable to procure an appropriate fantasy while masturbating.

Winston's been in the shower for about half an hour now, he must have a case of bater's block.

Sorry about taking so long in the bathroom, I had some bad bater's block. It was probably because of that Golden Girls marathon I just watched

baker's block 

When you want to bake everything, but can't decide on anything.

-"Sweet or savoury?"
-"I DONT KNOW!"
-"You're not helping my baker's block!"
