What you are describing is some of the symptoms of sexual addiction. Some men
get so addicted
to the pleasure and release they
get from
sex, that they want it whenever they can. It becomes a type of drug. The escalation that you describe is also a symptom of sexual addiction.
Too much sex can make somone numb. Why do you think porn stars retire after about 5-7 years? Sometimes men think that after a woman has children, she will never want sex again.
