What is a dilemma ??

Two men are having a drink in a bar.  

One says :  " You know, I've never really understood what a dilemma is .."

" Let me tell you a story, " says the other man, "Imagine you wake up in a bed with two people next to you.
To your left is an incredibly beautiful woman willing to have sex with you, and to your right is a very horny gay man."

"So where's the dilemma?" replies the first man.

"To whom do you turn your back ?"

Please take it easy, it's  just a joke !!
