18 Things Hugh Hefner Has Taught Us About Relationships

The famous octogenarian has had more conquests than most. Lucky for everyone, he's an open book.

1. Don't get married just because it's the thing to do.

2. Sleep with your sister-in-law to keep things interesting.

3. You might think you're not into dudes, but you don't know until you try!

4. Stay married for the kids.

5. Proximity to an ex does not necessarily kill your social life.

6. Don't just drop a former partner like they're yesterday's news because they might have stuff you can use.

7. Practice forgiveness when your ex-fiance starts blabbing about how bad you are in bed.

8. But if someone cheats on you, don't ever get over it.

9. Heartbreak should never ruin a good business relationship.

10. Make sure your employees are hot and then sleep with them.

11. Don't take getting sued by an ex-lover too seriously.

12. It's okay to use a mole to tell your twin girlfriends apart.

13. Your girlfriend will like it if you number her.

14. She will also like it if you refer to her as one of "the herd."

15. Film everything.

Not like that! Hefner is a notorious scrapbooker and his love of documenting his life spilled over into the SIX seasons of The Girl's Next Door, where he aired out his relationships with his three girlfriends in an edited fashion.

16. Treat your girlfriends like your kids.

17. Baby oil is the best way to keep things hot in the bedroom.

18. Most importantly: Having a "type" won't help you find love.
