scrotial itch 

The itching of a man junk when he is in the presence of a fuckable vagina.

As the bitch got naked I began to feel a scrotial itch toward her.

Acute Scrotal Itch (A.S.I.) 

The sudden sharp, piercing itching sensation a man gets in his scrotum. Often completely debilitating, the itch must be scratched almost immediately to avoid injury.

I was in the grocery store with my wife when I got an attack of Acute Scrotal Itch (A.S.I.). The aisle was crowded so I had to duck behind my wife to get to it.
