Speaking only for myself, I'm perfectly happy that the girl has healthy sexual appetites. I'm under no illusions that any of my real life partners are chaste virgins (with the exception of my high school girlfriend, many many years ago). I won't speculate on other players, but thinking out loud most people I know who are sexually active in real life understand that virginity isn't a common or even desirable trait in a girl. Sure, you don't want a cum ridden slut (I don't think Kaela is one btw) but it is ok for your partner to have some experience. And frankly, they're usually a LOT more fun in bed if they know what they like and what they want and what they're good at.
Back to the game, I do have a very real criticism that; the MC is a huge Mary Sue at this point. Not just because everyone and their literal mom is dying to fuck him (it is a harem game after all), but they also think the sun shines out of his ass. And why not, he is not only massively talented at everything. He's also flawless in his character. Polite, brave, kind, patient, diligent, charming (although he says he's bad at flirting, but not so bad it actually harms his romantic prospects...).
He's pretty boring at this point. He grew up alone in the woods, shouldn't he have some serious social problems? His parents abandoned him. No anger issues? He's been given a shit ton of responsibility by the people he cares about at age 18. No anxiety or negative coping skills. He is naturally talented and powerful. He could be reckless? He's got tons of women going after him at all times. Maybe he would value those relationships less since they came so easily to him?
I'm not saying rewrite or change anything. I think what you have works. I like your story and its definitely hot as hell.
But the problem is I like your story, which means I want it to be as good as possible, and in my mind, a flawless protagonist isn't worthy of what I think you're trying to create. That is to say, a VN that isn't JUST a porno, but a captivating game with adult elements.
Either way, best of luck to you.
