Well the storyline and style is clearly geared towards an adult female audience which is exactly what the Josei Genre is albeit there are maturity levels to it- Josei tends to be smuttier or more suggestive at minimum. This was clearly made with a female audience in mind even if the men are missing features especially due to the close attention to what women find attractive in the male features that ARE included. Now are they making porn? Yes. Are they making porn targeting male fantasies? Unlikely. This is clearly a woman's fantasy of being boned by handsome men. Men who write porn manhwa are 1: ugly asf 2: self insert themselves and therefore 3: would never ever make 3+ hot ass men bone a chick even if it paid the bills. They'd sooner make her smelly landlord do it. Bc thats closer to how he'd look.
Bottom line though just by reading this you can obviously tell it is targeted towards women. I dont think there is anything wrong with the josei tag as long as it is targeted towards women even if it is pornographic. Women also consume straight, gangbang, and kink porn in copious amounts.
You have no idea that tons of "josei" are doing smth called "dual targeting". Which means targeting towards both female and male gaze. I've come across male gaze pornhwa with very hot male MCs so they're not always ugly. Men also like gangbangs which is one woman and multiple men, it's an extremely common porn category.
If you guys didn't already know, there's been an issue of Korean artists creating smut manga that is basically pornhwa, but putting a josei tag on it.
Literally so many of these panels REMOVE THE GUYS EYES like a typical male gaze hentai and just mainly focuses on the woman.
It baits people with the cover image of hot guys. Rather than reverse harem, this might be more like a gangbang
