Inside the ladies-dominated varieties like bonobos, for-instance, same-gender matings is at least due to the fact well-known given that between-gender matings. Significantly, women bonobos has actually substantial, cantaloupe-measurements of labial swellings and you will common clitorises that can started to a couple and you can a half inches whenever vertical. Some primatologists have gone as much as to indicate the condition of the superior clitoris-it’s for the a frontal standing, as with human beings, and you can unlike within the pigs and you may sheep, which have clitorises in their vaginas-possess built to support exact same-intercourse vaginal friction.

The brand new dismissal from homosexuality within the animals, and treatments for particularly animals since freaks otherwise exceptions, helps reify negative attitudes into sexual minorities within the individuals
