Do they ever do anything X rated in front of the visitors?

Gorillas don't sort of exhibit that many X-rated behaviours like Bonobos do, which is probably too X-rated to even talk about. But gorillas do have some X-rated displays here at ZSL London Zoo. Probably our main culprit is our older female gorilla Zaire who pleasures herself quite regularly, unfortunately quite close up to the glass. We look at it here at the zoo as we are providing education, conservation, but also a form of sex education through the x-rated actions of the gorillas. But we do leave that part up to the parents to explain to their kids quite what she's doing. So she enjoys herself and we just leave her to it, obviously.
