It happens before qualifying for No-Nut November and Destroy Dick December. A challenge where you must not have sex for 30 days, even gay sex, or have any pleasure with another.

The rules of Self Sex September are as follows:

- You may not have any sex with any person, male or female; you can't even masturbate to another person.
(Masturbating to another one, will have yourself considered out)

- You may not watch any porn within the 30 day period.

- You may not ejaculate

- You may not have sex in your dreams.

- You can only masturbate to yourself, and you can wear any sexy girl clothes in the process.

- And finally, you can't hug anyone, even a pillow.

This game is technically just, keeping your hands to yourself.

After you complete the game, refresh yourself, by having a girl cum into your mouth. Then have a one month break period, before you qualify for No Nut November and then Destroy Dick December
