There are two questions here;
- Do ALL men cheat?
- Would ALL men cheat if given an "opening"?
Obviously, question 1 - No - many do not get the opporttunity.
Question 2 not all but perhaps many would.

I'm with eyslice on this I've never cheated on my wife but I've never put my self in that situation! If I was in that situation I can't honestly say that I wouldn't!
