hi dev team and all others!
Wanted to contribute and throw in my ideas as well. Don't wanna be contrary either, but I do agree with what others have said, that it doesn't make sense to have Asterion only be a bottom with the reasoning that being a top would require more self-confidence.
There's the idea that tops have to be confident, in control, and dominant, while bottoms have to be submissive, but that's not always the case. So, basically, what I'm trying to get at, is that I think once Asterion has the self-confidence for sex (and I fully agree he has to get to that point first), he could be either a top or bottom and have it still fit his character. If he was a top, he could be a service top like someone mentioned, or just let the MC guide him through it and show what it's like to simultaneously give and receive pleasure. Explicit example: having him lay back as the MC rides him (i.e. riding the bull lmao). Plus, I feel like getting to be with a top like that would be a very unique experience, one that isn't explored as much in other games, but would be awesome with the characters here.
Also, it was said that Asterion wouldn't have the confidence to top, but honestly, with the 'preparation' and initial discomfort often involved, being a new bottom can require even more confidence than being a new top, especially if bottoming isn't something the individual specifically really wants lol. Self-confidence isn't always the determiner in whether someone is okay with 'giving,' but it seems that part of Asterion's motivation is giving what he can to the MC, and if the MC wanted to be the bottom, it seems Asterion would be more comfortable with making that happen and being the top.
I know this turned into a full essay lol, and I don't wanna presume to understand the characters more than you, but I've been really loving the game, and largely because of the opportunities for choosing who your character is and what they do. Maybe it's just me trying to push what I want, but I know that at least my personal experience with the game would be really improved with the option to choose in this sense too. Either way tho, fantastic game and story, seriously love it, amazing job to all those who have worked on it!!!
