Commonly known as "sticking it up the wrong one". Anal Sex is something most of us claim to perform on our girlfriends/wives but nearly all of us never do.

Anal Sex is....

1) Something your mother is good at.
2) Dirty. That's why it's so good.
3) Something you'd gladly tell your friends you've done, but your girlfriend or wife would never tell a living soul.
4) What makes us all feel like porn stars.
5) Something your girlfriend or wife finds painful even if you have a small penis.
6) Something that requires a LOT OF LUBE.
7) Something that requires a condom. Unless you want what your wife or girlfriend had for their breakfast the day before on the end of your penis.
8) Smelly. See #2
9) Gives you entertainment afterwards by watching your girlfriend or wife's anus close.
10) Something that makes you erect just thinking about. Just like 99% of the men are just now reading this.
