Do you think men or woman cheat more ?

Actions begin in the mind ... More men think of cheating than women so as a natural corollary more men cheat than women even though they have lesser opportunities than women. Needless to say women have more opportunities to do so but since they don't think about it as much as their counterparts do they are behind in this race... For men sex is more a physical activity hence making it easier whereas for women it's more a emotional activity.
Looking at it from the evolutionary perspective looks like we have been built this way else mankind will perish either with over population or under population...
Purely my thoughts... Don't ask me for any evidence guys
