This is a touchy subject and my statements are merely conjecture to kick off a discussion:
Given the greater proportion of males to females using the service, is it fair to infer that men are more likely to cheat, or more likely to premeditate the act of being unfaithful?
If the latter, and we assume both sexes are just as likely to cheat, for women it's more likely to be an impulsive act - one of passion - whereas for men it's a planned behavior.
