domdrop
Domdrop is a brief period of depression that can occur after sex to the dominant partner/masochist in a BDSM situation. Subdrop is more frequently talked about, and potentially more common, but both can occur, and domdrop often involves feelings of guilt. Since post coital dysphoria, the medical term for sadness after sex, results from endorphins falling, the higher the fall, the bigger the drop; domdrop and subdrop most frequently occur after particularly intense sessions. The best management is physical affection, communication, reassurance, and time.
