Well, consider that "girl juice" has a smell too, but most people don't notice it because it's considered impolite to poke one's nose in there.
"Man juice" also smells, but likewise you only get specific opportunities to investigate it.
If you are intrigued, you may look up "Cowper's glands", which is where the relevant stuff comes from.
