Sex Weak 

The feeling of literally not being able to function because you are so weak from sex. You spend the next 4hrs being pathetic and partially retarded

"Hey Olive do you want to see a movie?"

"I can't! I'm so sex weak I can barely move!"

Weak sex is when you don’t have enough energy to fulfill your partners needs. It’s when your dick goes limp or your pussy gets dry.

Hey wanna have some weak sex?

Why would I want weak sex?
Cause it’s the best

Weaker Sex 

1) A term used to describe one gender as naturally inferior to another.

2) Pathetic attempts to copulate while lacking the desire to do so.

1) Argument: Women are the weaker sex because they're emotional, self-centered, vain and can't fight as well as men can.
Rebuttal: Men are the weaker sex because they're aloof, selfish, prideful and can't endure as well as women can.

2) I just keep getting weaker sex every time we try. I don't think I'm even attracted to my partner anymore.
