Smackie that is just a stereotype and its not true. I know loads of women who have a stronger sex drive than their partner, thousands of woman complain about their sex life on forums like this all the time.
As long as women like you make excuses for men by saying "they are men" they continue to get away with it.
How would you no whether their urge/instincts are stronger. You are a woman.
I would be just as hard on a woman who cheated as i am on men. What is your excuse for women cheating then if were so different to men?
The OP was driven by his emotions as bearz said-not his hormones. He was lonely, depressed, he was having an emotional affair which lead to him cheating. This wasnt even about sex-it was about him feeling like crap and she was there as a comfort.
It had nothing to do with animal instincts. Men and women are equal sexually, intellectually and emotionally.
The only ones who are driven by their hormones are sex addicts or men eho have abnormal levels of testosterone or vasopressin.
