Marital Infidelity – part 5

Brain Chemistry and Affairs
Is there a correlation between the levels of some brain chemicals and vulnerability to extra marital infidelity? Research in this area indicates that, while physical tendencies may be changed by our ability to think and reach logical decisions, our brain chemistry can influence our behaviors and choices. Of these chemicals, three in particular affect sexual and romantic behaviors in men and women. These are: Testosterone, Dopamine and Oxytocin. Elevated levels of these chemicals contribute to the development of lust, romantic love and attachment, all elements that play a role in intimate relationships and thus in affairs as well, separately or together.
Testosterone is a hormone associated with lust. While men tend to have higher elevations of testosterone than women, women can also be affected by this hormone’s levels. In women, lust waxes and wanes according to their menstrual cycle, typically reaching a peak during ovulation – the second week of the menstrual cycle – which is also their most fertile time (Havelick.)
Studies indicate that people with high circulating levels of testosterone tend to have more affairs and higher divorce rates than those with lower testosterone levels. And, while some people may have inherited high testosterone levels, certain situations can also elevate or lower them. For instance, single men have higher testosterone levels than married men. In married men, when marriages are in trouble, levels of testosterone raise (Booth and Dobbs), making affairs more likely to occur.
Dopamine, our most powerful stimulant, is a neurotransmitter that becomes elevated in addictions, and is also elevated when we are in love, contributing to hyper-focused attention, exhilaration, obsessive thinking and increased levels of energy (Fisher.) Research found that novelty (like in an affair) can trigger the release of dopamine and promote romantic love. Dopamine, in turn, stimulates the release of testosterone, which increases one’s sexual drive.
Oxytocin is called the “cuddle hormone’ because of the role it plays in intimacy. The role of oxytocin in affairs seems to be particularly important when we consider affairs women engage in. Women, in fact, tend to have affairs because they are looking for a soul mate, someone they feel emotionally connected to, and with whom they can share their innermost feelings (Spring.) Men, on the other hand, are more likely to look for a playmate, someone with whom they can engage in activities and pursuits they both like and enjoy, including sex.
As we can see, “Love is a symphony of feelings with many notes and chords,” as author Helen Fisher tells us in her book “Why we Love.” There are many elements – we discussed the psychological, environmental and physiological ones – that contribute to making it as exciting, attractive and irresistible as it is, at all ages and under all kinds of circumstances. But, while its elements have been the same throughout history, new technological developments have created circumstances and opportunities for the development and expression of lust and romantic love that are completely new. Internet affairs are examples of such new circumstances, providing hitherto new and fantasy rich romantic and lustful encounters for both men and women.
In the following blog post we are going to address Internet affairs, and discuss the similarities and differences between them and more traditional ones.
