I do so agree with you!!!
Dominance is the only reason for Homosexual Acts in animals.
My lesbian sister and her daughter were discussing this with me. My sister said that animals are homosexuals. My niece, (who worked for an Adult toy shop at the time {yes, messed is the word for that family}), said that only two animals have sex for pleasure. Humans and Dophins. All others do it for dominance.
I like the cannibalism statement. It about sums it up!
Oh, I wouldn't say that. Reproduction is more of a surface drive with them than with us. They may not do it for pure pleasure, but when some female dog is in heat, they male dogs sniffing around her house aren't thinking, "I can't wait to show my dominance!"
