I don't think we've ever hit on this topic before... and I was thinking about it because of the Cicada. I was thinking, what if a gay Cicada comes out of the ground after 17 years and is just flying around thinking, "Hey guys, what's goin on, what's all this buzz about, I don't get it?" It appears that zoos have some gay animals and some tours to prove it. http://www.swissinfo.org/sen/Swissinfo.html?siteSect=511&sid=1841425
I learned in my primate behavior class that Pygmy Chimps have homosexual tendencies, they also masturbate, and IIRC are incestuous.
