What is genetic sexual attraction?

In the wake of incest charges filed against a 36-year-old woman and her 19-year-old son, Monica Mares and Caleb Peterson are hoping to raise awareness about genetic sexual attraction.

The two have been romantically involved for months, and face up to 18 months in jail. Mares has said that she is willing to give up her eight other children in order to be with Peterson.

How could two relatives be sexually attracted to each other?

The Encyclopedia of World Problems and Human Potential says Genetic Sexual Attraction is:

Experienced between mothers and sons, fathers and daughters, and between more distant relatives, but most common between siblings of opposite sex who bear a close resemblance. It takes the form of an overpowering, almost electrical grip of emotion, associated with an inability to keep away from the other person and an almost primordial sense of having belonged together all their lives. The attraction gives rise to a sense of underlying shame and guilt, together with a feeling of rejection that may prevent effective communication because the emotions are too threatening to share with anyone. This may be compounded by any sexual relationship resulting from the attraction.

Adoption rights advocates write about GSA being a frequently noted response to reunion. They say family members experiencing GSA might feel the need to touch, spend time together, talk and share.

Further explanations say those feelings are prompted by having similar characteristics to a person, feeling more comfortable with those similarities and the subconscious memory of a family member’s smell causing a physical reaction. The turn to a sexual desire turns genetic attraction to genetic sexual attraction.

Experts on the subject recommend giving feelings time to settle back into a proper context and seeking counseling from experienced adoption therapists, KOKI reported.
