Is it normal that i play with bottle caps in my mouth a certain way?
Okay so its been a while but I recently discovered the parotid duct openings inside my mouth because one day while playing with a bottle cap I placed it inside my mouth. Where the opening is on the inside of my cheek and id press down on the bottle cap from the outside of the cheek to create a vaccume. Its the most weirdest feeling that travels through the cheek. Has anyone ever done this?
