When life gets rough - I turn to the teachings of Confucious.
Confucious say...
Wife who put husband in doghouse soon find him in cat house.
Man with tight trousers is pressing his luck.
Foolish man give wife grand piano, wise man give wife upright organ.
Secretary not permanent fixture until screwed on top of desk.
Passionate kiss like spider's web, soon lead to undoing of fly.
Man's wife his better half, his mistress his better whole.
It is good for girl to meet boy in park, but better for boy to park meat in girl.
But seriously - unless you can magically pull of the almighty threesome (you'll still get that awkwardness afterwards) then risk is greater than reward.
Totally read the last couple of chapters in "The Game" by Neil Strauss if you want that fighting chance
