(1) Pairing copulations are preceded by females indicating their willingness to copulate by adopting the receptive position; females lie flat in the water to allow the male to mount.(2) So if we have one man and one woman who copulate in the standard way, and not in any kind of other way that we find troubling, then they can raise children.(3) As adults, men look at porn because they are, u251cu00f6u251cu00e7u251cu2510unnaturallyu251cu00f6u251cu00e7u251cu00fb one might say, hormonally driven to copulate with multiple partners but unable to do so.(4) Most species perform prelaying courtship feeding, which conflicts with mate guarding, and copulate frequently.(5) If it was previously in doubt, we now know that unmarried sexual partners can copulate without going to prison.(6) In the case of humans, the last male to copulate would be in a position to displace the semen left by previous males before inseminating the female with his own semen.(7) In the laboratory, golden egg bugs copulate repeatedly, with copulations often lasting [greater than] 10 hours.(8) It is very rare for already mated females to copulate on the sly with males who are socially subordinate to their current mates.(9) Also, males cannot force females to copulate as copulation is only possible when the female assumes a horizontal body posture.(10) after about twenty minutes, they copulate again(11) However they are not expected to love them, just copulate with them.(12) It's that plain and simple: find a mate, copulate , produce offspring, raise it, set it off into the world when the time comes, retire. That's what the Unromantics say.(13) Third, males may attempt to copulate with their social mate as frequently as possible to win the sperm competition battle.(14) In the sexual race, worms have hermaphroditic sexual organs, and copulate and then lay cocoons filled with several fertilized eggs.(15) u251cu00f6u251cu00e7u251cu2510They are renowned for their rather large [male] copulatory organ,u251cu00f6u251cu00e7u251cu00fb says Horne.(16) But certainly across the primates, and I've watched quite a lot of primates copulating, there's remarkably little indication that the female gets any pleasure whatsoever from a rather transitory brief copulatory encounter.
