I have a feeling the popular one would be woman being the aggressor, but I might be wrong
Not really.
You very likely right.
There are too many (in particular SH)
where its the man, topping women.
But also bc the demography of authors is male, readers are male. Hence logical to write a MALE MC in control in smut.
And even if there are "female authors" they mostly write yuri/futa or non-smut.
So, like the old logic : what is rare is precious (/popular)
So yes, a top woman series would be popular currently, on SH.
But who could write a good one, depends on author. Just like not anyone could have done Onepunch-man despite clearly easy premise.
PS : a top woman, with a male MC/Protag. A female protag/pov would turn off male readers.
Depends on how aggresive we are talking about. Also depends on the readerbase. In my experience of reading shoujo and josei, works targeted at women, women are rarely an aggressor\top.
Welp sailus also explained the same thing, in shortened form.
As expected from the Immortal Sage of SH.
