As a man I find this offensive. I see it as a privative way to mark a woman as a possession.
I am probably way too old school but I think is a way to dominate and degrade - you are worthy of spit.
As far as us guys wearing your fluids while going down? Well we trade fluids all the time. Yet spunking your face? I can bet you that there are very few long lasting relationships where the man degrades the woman in this way.
Respect yourself.
