Chimpanzees and bonobos both do oral sex (and everything else, barring S&M). Macaques females do mounted genital rubbing - so do birds, actually.<quoted text>
Amusing. You reveal a lot about yourself with that one.
A female, gay or straight, would require the proper apparatus on the animal to get any physical stimulation from it. Not too many animals they can count on to give them a satisfactory cunnilingus session.
A straight male would be interested in available orifices, the first instinct being the one designed for such use. Less teeth, and the tail wouldn't be so much in the way.
This would require an animal of the opposite sex.
Now, Timmy and his gay buddies can go with either sex. All they have to do is lift that tail and have at that universal orifice they consider a sex organ. Don't even have to lift the tail with their buddies.
You guys are nasty.
Once again, you've expressed gross ignorance.
