SPANKING

About 2 weeks ago i was honestly being a brat i yelled out about alot of frustrating things and told my husband "whats the point of telling you anything you don't do shit and i can pretty much get away with anything just wishing you gave a fuck" well i think i triggered something cause at that moment he spanked me i was shocked but the built anger just disappeared it was very weird i was calmer and our relationship was almost instantly fixed now... i looked it up and this is common in some relationships it's called DOMESTIC DISCIPLINE he hasn't done it again since but then again ive been pretty calm lately has anyone ever heard if this or tried it? Do i subconsciously want to spanked? I always have a very alpha personality do i want to be submissive? What is this?!
