shooting blanks into a dead end

When both partners of a relationship have been fixed and can't get pregnant. The male has had a vasectomy and the female her tubes tied or a hysterectomy. The male therefore does not have sperm in his ejaculate and the female no way to deliver an egg to be impregnated.

Female 1: "The sex with Joe was great last night. I love not using a condom."
Female 2: "Hey aren't you guys afraid you'll get pregnant?"
Female1: "We're both fixed. He's shooting blanks into a dead end!"

Going Down a Dead End

When someone is hitting on someone not interested in their gender.

Hey Greg, you know that girl Sarah that you were hitting on…well don’t go down that street…she’s pretty lesbo…trust me you’re going down a dead end.
