How many married men don't cheat-?

There is no way to have an exact number as to how many married men don't cheat. In order to know how many men do and do not cheat, all cheating men would have to admit to it and that does not happen.

Estimates range from 25% to 75% are unfaithful, and of course these numbers would vary widely between countries. The best answer might be around 80% of men do not cheat.
