There is hardly a weaker connection between the titular signifiers and natural reproduction than in same-sex sexuality. Though seemingly non-functional for natural reproduction, it has a firm place in evolution, having been described in 450 and noted in 1500 animal species. Some genetic theories that have attempted to explain the mechanism in humans are briefly outlined and annotated. Same-sex sexuality (between men more visibly than between women) is present throughout written history, marked by varying forms and degrees of sexual discipline. The paper includes historical review, epistemological consideration, and clinical experience. The vicissitude of same-sex sexuality is interesting per se, but it also corroborates the initial premise that it is a biologically supported mechanism, as it survived even the most unfavourable regimes. The author argues that the gender of the subject and the object are two sides of the same function that benefits reproduction by varying and combining gender-related properties. Sexual activities are more susceptible to discipline, but in an unexpected sense.
