Affectionate touching releases oxytocin. This makes for fondness between husband and wife; it also makes a mother's breastfeeding and contact with small children pleasurable and emotionally satisfying.
Needless to say, the interplay of both,(male/female, testosterone/oxytocin) is essential for the continuation of the human race via a strong drive for intercourse, followed by the maintenance of the wife/husband bond and the mother/child bond.
Get two men together sexually, and it goes haywire, it's like testosterone2: aggressive lustful behavior, frequent impersonal sexual contact, little pair bonding. Two women, the converse: oxytocin2.
One might think that this would make women's homosexuality more permanent, but it has a paradoxical opposite effect as well: when women break up, they feel deeply wounded and broken-hearted, so they often don't "move on" to another partner. They may decide to try a kind of defensive abstinence, or invest their emotional energy into their child, or into God/spirituality.
But gay men are more likely to just keep pinballing around from partner to partner.
Like all generalizations, this of course runs into all kinds of particular exceptions. But as a general observation, it's what I've seen.
very interesting post.
I think that is much the case, is just another example of the wise perception i often see among posters on FR. Thank God, who created and joined man and women for more than just sex and procreation.
