In the dog world it has nothing to do with sex. It's a dogs way of showing dominance over another dog. If your dog does it to you then your dog is telling you and your friends that they own you. You pay the bills but they own the house and everything in it.
If the dog doesn't do it to you but does it to others then the dog sees you as the leader and the others as lower then them in the pecking order.
