I fail to see how this 'fact' could possibly have been cataloged for all of the species in the world. This seems to be a simple,. sophomoric, "I find homosexuals icky" kind of argument. I find it odd how most of the commentators here seem to focus only on a single sex act that can be practiced by both male homosexual couples and heterosexual couples. Why is there no similar, "it is just gross" kind of talk about female homosexual sex?
