A 369 is when 2 women are doing a 69 and you have sex with the woman on top from behind at the same time. Also see 370.
They were doing a 69 so I got behind the top girl and started pounding her from behind at the same time. Love doing a 369!

It can have a lot of different meanings. 369 is an angel number. This number is only hot peoples favorite. It's also a message about your social life and communication skills. Your guardian angels want you to create better relationships. When you use this number a lot you want to hint at people that you are in a healthy and strong relationship (most of the time a gay relation) that had up and downs in the past but is now stable. You broke through the glass after some time and you are really happy now. 369 can also stand for something you've been you're whole life but was hard to accept. People who love this number are really lovely.
"My favorite number is 369"
"Oh, well you must be in a healthy gay relationship then!"
