Its all about deceipt and lying.
If the other partner is aware and by "not objecting to the activity" thereby condoning the behavior, then it changes from cheating to abnormal marital behavior.
The reasons given for the female cheating in this website is very simplistic and generalised.
Women are just as complex as men in the many reasons they use to justify extramarital events, many of which are NOT emotional affairs, but driven by deeper and possibly less socially aceptable instincts.
(Nature or Nurture?)
