How to stop a young dog from crotch sniffing?

My aunt has a young Labradoodle (pretty big in size) who will NOT stop sniffing my crotch, I don't want to push him away cause he's a young dog, of course he will take it for play and start fucking the shit out my leg (also a problem).

I hardly get to see my Aunt and her annoying dog so I can't really train him to stop and I don't want to confront her about it or anyone. I just need a good strategy to make him stop. :)

I am also a very hygienic person so cleanliness isn't a problem.
