The 3some plus rule

Having sexual relations with a female and her friend is always acceptable as long as the total score of said bitches hotness equals 10 or more.

The 3some plus rule

While having sex with a 9, one only needs to include a 2 or greater to make said intercourse awesome and braggable.

Coversely, having sex with a 5 and a 4 is just average and the particapator should be ridiculed for banging 2 Gremlins.

In extreme situations the hotness scale can be ignored for certain features such as huge tits or no gag reflex. Of course these attributes must be reviewed by a panel of your peers.

The rules you must follow if you are a guy to become a male porn star.

THE RULE OF 8
You must be able to go, with out blowing your load, for 88 minutes (average of 6 times longer than a normal session)

You must live in the 831 area code (not sure really, but Northern Hollywood...so around there)

You must be at least 8 inches....that gets most guys caught lying through their teeth (length is important, if it's too small, you can't see it on camera)

Three Tattoo Rule 

The scientific rule that states "If a girl has more than three tattoos, she'll probably take it in the ass."

1.) At first, I didn't buy into the Three Tattoo Rule, but eight years later and a few more romantic encounters under my belt, I'd have to say it's true.

2.) Cindy didn't disappoint. She was covered in ink and reaffirmed my belief in the Three Tattoo Rule.
