June 9
The day in which couples (gay or straight) celebrate sex by having sex. The reason National Fuck Day is on June 9th is because 6/9 closely resembles the popular sex position 69.
Honey, today is National Fuck Day! Let's fuck!!!

If National Fuck Day is my half-birthday, does it still count as ABC Sex?

8/6 (August Sex)

This is a day celebrating variety in sex partners, and just going for it.

Remember:

"If you're with someone new, you know what to do!"

This is also a great day to try skydiving, pearl diving, bottle spinning, or just anything you have always wanted to do but just haven't yet.
My hopeful fuck buddy was ready to call it a night, but I said, "Why don't you come on over to my place instead? It's national fuck day!!"
