Jaqueline Calleja comments on the sexual complementarity of same sex couples.
Sexual attraction and expression differs for each individual. Sexual fulfilment can be achieved in a myriad of ways that do not necessarily involve both male and female genitals. I've often read that the most important sex organ the human being has is the brain.
The complementarity in same sex couples is based on their attraction and love for each other and this includes the desire for sexual intimacy. I can assure Ms Calleja that our ability "to generate light" is not in the least affected. In fact, some studies on sexuality found that orgasm is much more common among lesbians than heterosexual women.
Gay people are not infertile and increasingly, more of us are choosing to be parents. The children of same sex couples are likely to be more loved and cared for because for us, parenthood is not simply an accident which happens as a consequence of sex, but an event which requires deliberate planning.
Since we are intelligent and creative beings, "a village hypothetically inhabited solely by homosexual couples" would acknowledge the need for sperm banks and surrogate mothers, and is, therefore, as likely to flourish as one populated by heterosexuals.
Since same sex couples generate mostly heterosexual offspring, the village would soon cease to be populated solely by gay people.
