Shes a woman thats why
Women dont have to be consistent or logical
If the woman begins to feel bad, ie regret, a comsentual thing she willingly did for an unspoken or spoken quid pro quo, or even no quid pro quo,
She can change her mind and decide to be a victim and destroy that mans life.
...hardly seems fair. But I have been married for 30 years, so yeah, logic does not apply.
