&gt; That&#x27;s not sex. You can&#x27;t impregnate a female by grabbing.<p>The whole point here is that sex != reproduction.  IE social sex constructs, homosexuality, conflict resolution through sex, and just recreation via sex.<p>&gt; Also, having lots of sex in a 10 day period is impressive, but humans don&#x27;t have a 10 day heat period. They&#x27;re in heat all the time. Its not really comparable.<p>It&#x27;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.<p>Sexual swelling in bonobos, for example, is almost consistent throughout the cycle.
