Also, having lots of sex in a 10 day period is impressive, but humans don't have a 10 day heat period. They're in heat all the time. Its not really comparable.
I think we can split hairs all day, but I don't think its controversial to say that animal mating and human mating evolved in very different ways. Obviously our closest relatives in the animal kingdom will be most like us, but even they have heat periods.
The whole point here is that sex != reproduction. IE social sex constructs, homosexuality, conflict resolution through sex, and just recreation via sex.

It's true that humans are available for sex all the time - a claim no other mammal can make as I understand it - but chimps and bonobos are also available for sex far more often than they are in a viable reproductive state.
Sexual swelling in bonobos, for example, is almost consistent throughout the cycle.

They actually do greetings by involving their reproduction organs.

Bonobos and chimps don't have too. They do make sex all the time. Google "concealed ovulation." That's the evolved mechanism where female never signals when it actually ovulates. And it's present by bonobos.
Please name percentage that supports your "typically" claim. It depends what you want to count.
If we count our closest relatives, they are bonobos and chimps.

"The majority of chimpanzee reproductive behavior is promiscuous, with females mating with multiple males opportunistically during estrus, though the majority of copulation occurs during the 10-day period of maximal tumescence (Goodall 1986)."
The observations of Goodall were disputed by some stupid male "scientist" who claimed that she "projects her values to chimpanzees." But she observed the behavior in the nature, documented it and published. He was the one who "projected."
100% of our closest relatives are provably promiscuous.
And some of them do copulate with the same sex too.
