english: Interestingly, chimps have sexual swellings through 40 percent, roughly, of their menstrual cycle, bonobos 90 percent, and humans are among the only species on the planet where the female is available for sex throughout the menstrual cycle, whether she's menstruating, whether she's post-menopausal, whether she's already pregnant.
non_english: Interesantno je da šimpanze imaju seksualno naduvavanje tokom, otprilike, 40 posto svog menstrualnog ciklusa, bonobo šimpanze - 90 posto, a ljudi su skoro jedina vrsta na planeti gde su ženke spremne za seks tokom celog menstrualnog ciklusa, bilo da imaju menstruaciju, bilo da su u menopauzi, bilo da su već trudne.
