I am guessing that most, if not all, of us "breeders" have seen attractive members of the opposite sex and wondered what mating with them would be like. In most cases, we can't even work up enough nerve to say "hi" and that thought, like so many thousands of others, leaves us almost as quickly as it came.
It’s remarkable how controversial it is to observe that a person may want to do something, but he or she does not have to do it.
