Just so you know, this won't actually teach you how to stop subdropping, why you drop, or how to get over a subdrop. The title is a lie.
For those of you who don't know, subdropping is something that happens to (you guessed it) submissives after a scene.
The most common subdrop I know of is caused by an endorphin rush after a scene finishes. The sub is usually filled with intense emotion either by climax, pleasing their dom, or anything else that can happen in subspace....
