>>813394>you're telling me, that woman backs that phat ass up against your crotch while you are snuggled in your bamboo shelter and it's raining outside, and your arm is wrapped around her belly, just beneath her breasts, and she shifts her ass so your dick is between her legs, and you can feel the heat of her loins on your dick, you wont have the will to fuck?>because I sure would.Our most primitive biological needs are able to produce cold, thirst, and hunger responses that feel so life threatening they make you forget anything else exists. Few people have felt this.
Sex also has primitive controls inhibiting it between strangers or during harsh conditions.
So basically they get there as strangers, and by the time they know each other enough to fuck they're too cold and starving to care.
Basic resources aren't remotely scarce in our world so we don't understand things like true hunger. Sex meanwhile is still scarce enough that we expect 2 naked strangers to eventually do it.
