Female authors tend to portray male doms as having more extreme thoughts than they tend to actually have xD I think most male doms dont really think "punch her in the face" as their main fantasy. I'm sure there are some, but I dont think it's most. Or maybe it's a thing for female dommes? With men being less likely to want to seriously harm a woman, vs women wanting to test how "durable" a man is? Cant speak for them.
But from what I gather, the dom having such thoughts is a turn on for a lot of masochistic women, at least as a fantasy. Tbf, masochists in general tend to have more extreme fantasies than most sadists. At least, in my experience.
