I don't know what dude could be attracted to a damn animal of any sort let alone get hard enough to actually be able scrump it...
I dont think men need to be attracted with whatever they're screwing. thats why they can get prostitues off the street, etc. NOT ALL MEN...but as an overgeneralization. im sure many men on this board could claim to waking up with some girl that they would never want to be seen with, but took her home anyway just to get laid. at least the animal wouldnt have to pay for therapy for the rest of its life!
