It is a natural dog behavior to smell "that area" on other dogs and people, because this is how dogs gain information about the person/dog that they're smelling. Much like people get to know other people by what their faces look like, dogs tell people (and other dogs) apart by their smell, and the part of the body where that individual smell is strongest is, well, the groin/rear. So, it is just how the dog tells you apart from other people.

A dogs sense of smell is so acute that it can smell a person who was in a place days after.
