Is sexual orientation a myth?
What are we to make of ‘sexual orientation’?
If many adolescents experience bisexual attraction, if some people change their orientation, if most homosexuals are actually bisexual, and if diverse sexual practices can become strongly addictive, is a fixed orientation actually a myth?
Studies of twins
Studies of identical twins have repeatedly shown that sexual orientation is not determined genetically. Identical twins with identical genes do not always have the same orientation. If one is homosexual, the other is far more likely to be heterosexual. Even though statistically, compared with the general population, there is an increased chance that the twin will be homosexual, this is far from guaranteed. So though there may be a genetic ‘tendency’ toward homosexuality, sexual orientation is not genetically ‘determined’.
Sex and sexuality
Marriage is under attack in the UK. It has been humanity’s default mode of handling sexuality since the dawn of time. Whether or not it was accompanied by public ceremonies or religious rites, heterosexual marriage has been normative. Polygamy, by far the commonest alternative arrangement, has been the habit of only a few.
Such bonding is quite remarkable. Imagine what life would be like without it. If we treated sexual partners like holiday vacations, rarely returning to the same place twice, men would never know how many children they have or who they are. Women would be given the entire responsibility of bringing them up and providing for them. A moment’s thought shows how logical and inevitable heterosexual marriage is.
