I don't know why, but this cracked me up...
NZ Herald: Female koalas indulge in lesbian "sex sessions", rejecting male suitors and attempting to mate with each other, sometimes up to five at a time, according to researchers.
The furry, eucalyptus-eating creatures appear to develop this tendency for same-sex liaisons when they are in captivity. In the wild, they remain heterosexual.
Scientists monitoring the marsupials with digital cameras counted three homosexual interactions for every heterosexual one.
"Some females rejected the advances of males that were in their enclosures, only to become willing participants in homosexual encounters immediately after," say the researchers.
"On several occasions more than one pair of females shared the same pole, and multiple females mounted each other simultaneously. At least one multiple encounter involved five female koalas.
My husband cautioned me not to make a snarky remark about the necessity of men when all your needs are seen to by others lest you think I was being disingenuous with my Valentine's dedication, so for his sake, I'll refrain. I can just imagine homophobes' heads spinning when they bring their little impressionable children to the zoo and find the cute koalas in a five way lesbian encounter.
