"When I came out of the closet I was blackmailed, threatened, even bribed. But of all the shocking words that were said to me, three stood out in particular - 'It's not natural'." The idea that certain behaviour is "unnatural" is often used to justify bigotry, especially against people who are LGBT, polyamorous, or in any way non-traditional. But is it true? Antonia Forster is a bisexual, non-monogamous biologist that wants to set the record straight. What does "natural" mean? Can animals be gay? Are there always two sexes? Prepare to see the animal kingdom as you've never seen it before... Antonia Forster is a science presenter, comedian, and rapper. Antonia believes communicating science should be fun as well as facty. So stay tuned right to the end for her rap about the diverse sexual practices of the animal kingdom!
