Beta male losers like this self-sabotage. They feel intrinsically unworthy of landing a girl "out of their league" because they're chronically insecure around her and their fragile little egos can't handle the thought of being dumped. So they pull the trigger first and go back to bestiality, where they never have to face the prospect of bettering themselves. Zoophiles are as despicable as the livestock they shack up with.
