You knew it had to happen sometime. A husband discovers that he and his wife have the same sperm donor father. (Both of them raised by lesbian parents.) That means he married his half-sister, who is now the mother of their three children. What should they do?

Although the story has not, to my knowledge, been verified, it was the subject of a question submitted to Emily Yoffe, author of the Dear Prudence advice column. The husband explained that when he met his wife in college, “the attraction was immediate, and we quickly became inseparable. We had a number of things in common,” and so, he writes, “everything was very natural between us.”

Of course, thousands of other couples have experienced an immediate attraction that turned into a lasting relationship, but there’s an added factor here. Did this couple experience GSA, genetic sexual attraction?

According to the Genetic Sexual Attraction website, “Genetic Sexual Attraction or GSA occurs between two adults who have been separated during the critical years of development and bonding and are reunited years later as adults. When these ‘strangers’ finally meet, the brain struggles to associate each other as family. Instead, they become captivated with one another, sharing similar physical features, likes and dislikes.”

Is that what this couple experienced? And what does this do to the “born that way” argument commonly used by gay activists to support their case that “gay rights” equals “black civil rights”? In the case of homosexuality, there remains no reputable scientific evidence that anyone is born gay (although there are certainly genetic contributions to homosexuality, as opposed to genetic causes). In the case of GSA, there could really be deeper genetic factors at work, yet there is only one viable response when it comes to separated siblings who meet later in the life and are attracted to each other: They must resist what their genes want them to do.
