I've been picking up that I shouldn't be one (as a guy not me specifically) to ask and should just do it? What does just do it mean? Clearly it means sex, but how do I progress it from stares across the room to just plain fucking in the work restroom.

If there's a needed example then I'll provide but I seem to be the one on the out and perhaps this can be answered in a macro sense. (I'm autistic by the way)
