>>97528149Simplistic version:
Top = active partner
Bottom = receptive partner
(This includes pentrator/penetrated, but can also refer to the partner doing most of the work; a woman riding a man cowboy would be a top, even though she's being penetrated.)
Dom = tells partner what to do
Sub = gets told what to do
The term "service top" is one I like, referring to people
like me who like pounding away but also like getting instructions on what to do/not do.
Unfortunately it seems like once you get down to the actual fucking, virtually every woman in the world turns sub.
