13. You brag about your smokin' hot wife.
You do this to:
a.) show other men that you are better than them because you scored a more attractive woman.
b.) indicate to other men that you are having more/better/kinkier sex than they are (even if they don't find your wife all that hot) so they should respect and envy you.
c.) remind your wife what she owes you. She exists for you. She better deliver.
d.) make every other woman in the room wonder (even for a moment) if greater sexual fulfilment could be found in your arms...
