A vacation driving through Scotland and Wales on the old highways was absolutely the best thing I ever did in my life so far. It was the mid 80's. And I ain't talking just the awesomeness of landscape, which there is. I include 80's Glasgow as part of the whole picture, kinda like Gotham City come alive.

from deep within our unconsciousness

I think about this part of it all a lot! I.E., theoretically if all systems were working optimally, we'd be attracted to the best DNA mix to throw into our own. So someone or something quite the opposite. And that's what the fantasies are about? On the other hand, when you actually get into it, a big part of actual sex is craving for physical intimacy, even men who want just one night stands are looking for touch skin to skin. Likewise, women who have infants lose desire, I think not just because of hormones but because the infant is providing physical intimacy to the point of too much. You lose yourself in the intimacy, it's just the two of you, the rest of the world shut out and that includes intense experience of orgasm where you want to feel safe with each other, not challenged by a totally different kind of person, with totally different DNA, from a tribe you are not necessarily comfortable with.

If you really want to get into deep thoughts over this, there's also the mind over matter, become a higher being than a slave to reproductive urges thingie:

How would Gandhi’s celibacy tests with naked women be seen today?

By Ian Jack @ TheGuardian.com, Oct. 1

[....] For several decades after his death, this episode was not widely known. Popular accounts of Gandhi’s life, including Richard Attenborough’s biopic, never mentioned it.The facts are that after his wife, Kasturba, died in 1944, Gandhi began the habit of sharing his bed with naked young women: his personal doctor, Sushila Nayar, and his grandnieces Abha and Manu, who were then in their late teens and about 60 years younger than him.

Gandhi hadn’t had a sexual relationship with a woman for 40 years. Nor, in any obvious way and so far as anyone can tell, did he begin one now. His conscious purpose in inviting naked women to share his bed was, paradoxically, to avoid having sex with them. They were there as a temptation: if he wasn’t aroused by their presence, he could be reassured he’d achieved brahmacharya, a Hindu concept of celibate self-control. According to Gandhi, a person who had such control was “one who never has any lustful intention, who by constant attendance upon God has become proof against conscious or unconscious emissions, who is capable of lying naked with naked women, however beautiful they may be, without being in any manner sexually excited”. Such a person, Gandhi wrote, would be incapable of lying or harming anyone.

Why was this so important to Gandhi at that time? Because he believed – fantastically, egotistically – that the Hindu-Muslim violence then sweeping India had some connection to his own failings [....]

Roman Catholic doctrine about priests and honoring celibate saints would agree....we know how that's working out lately
