As I am a guy, I can relate easier to a male protagonist... The issue though, is that with most Erotic/Adult VN/Games, the male protagonists have this tendency to be hollow perverts who just want to screw every women that exists... Their thoughts are focused on sex almost all the time, and they really have very little emotional attachment to most of the women they eventually do have sex with... And what's worse, is that most of the time, they never develop beyond that stereotype... And I think it's because many developers just find it easier that way, as they don't have to overthink the character or put much effort into proper character growth and emotional/mental development... It's really just a cop out, much of the time...
Now, with female protagonist, 9 times out of 10, the developers have no real clue how women really think, act, and/or react... So instead they default to stereotypes or their male perception of a woman... So, they are typically treated as either oversexualized college partygoers, and/or naïve and easily manipulated, and/or professionals that are easily corruptible, and/or are unwitting targets of any/all perversions the developer can dream up (the victim), etc... It's not very often, where they are treated like a more realistic and strong woman, who is in charge of her own fate... A true protagonist, rather then just a walking target with breasts...
Sure, I'ld love to see more Female Protagonist Characters taking the lead role rather then being used as targets for other characters perversions... But those are very rare... And I'm fairly certain that most developers of these things, are guys... So unless they have the proper experience, training, etc... In order to have a better insight into the mind and actions of a real woman, outside of what they've seen in a movie or read in one of these VN/Games... I don't see it changing anytime soon... Which is sad...
I'm not saying all guy developers have no real clue how to write in a proper female character... But it's not often you sense that the developer has any clue, with most female protagonists, let alone supporting characters, that already exist in most VN/Games on the market... You get some winners now and then, but it's not the norm...
