Affectionate touching releases oxy. Cuddling a child or pet is pleasurable because of oxytocin. An infant suckling releases the mother’s oxytocin, making nursing pleasurable for women.
Individuals who regularly cuddle can become addicted to each other. They can experience oxytocin withdrawal when apart.
Oxy releases cyclically. Couples reach the highest levels of sexual feeling by alternating about twenty minutes of intense touching with relaxation or less intense touching.
Orgasm spikes oxy to five times normal levels. The refractory or disinterested period some people feel after sex may be due in part to oxy-tocin overdose (too much of any drug reduces sexual interest). Test this hypothesis by cuddling more when you’re not having sex, to get your brain used to oxytocin.
