.June's Saturn I even explained to him, that it's like a person who feels lust for an animal.
I don't even think it's that simple. I mean as you said last is a human trait, so it's like us having the trait of another species...The behavioural instincts of another species.
Say like a bird has the trait or instinct to build nests. It's like a human suddenly collecting sticks and twigs and trying to build a nest.....then settling down to roost, picture that!!! It was something utterly contrary to their nature - like nest building is to us!!
