Closet Sex 

When you crash at a friends house or vise versa and you start snuggling, or other doing sexual activities, but you both act like you're straight and pretend like nothing happened in the morning.

Essentially a one night stand, but for gay or bisexual people who are too shy to come out of the closet.

Example 1:
Jacob: "Morning dude"
Carl: "Hey."
Jacob (thinking to himself): "That guy gives the best hand jobs iv'e ever had"

Example 2:
Steve: "So how'd the party go"
John: "Pretty good. I'm almost positive Jacob and Carl were having Closet Sex after they thought I fell asleep though."

when you live with roommates but can't wait for an empty house to get it on, so you have sex in your walk-in-closet to keep the noise down

Babe, I really want you right now! Ahh, I wish we were alone. Can you be quiet? Not really...it's not that fun that way. Okay, let's go for some closet sex.

Closet Sex: when your fucking a girl just because its an easy lay, but you dont tell your friends because shes fat or ugly.. so you keep her in the "closet"
