Sorry to not soften this blow, but none of that is going to happen in GL. Kevin's short answer is probably going to be "We aren't cloning our clone." The longer answer is a bit more complicated.
We are not doing a male MC. The transformation is immediate, during the intro, which is why it works. To have a male MC, it would require either every available event to have a gate to block it until full womanhood is reached, or alternate pics for every event of a male. Then we would need a LOT of build up events to reach full womanhood. (This is Girl Life, not Boy Life) All of that would essentially be an entire new game, which ... is what Clean Slate is. And it's a great game. But they aren't really the same type of game. Clean Slate, like Girl Life, is a sandbox. In my opinion though, it is NOT a life sim. Girl Life is. CS has an overall storyline, and it has to be completed in certain steps to unlock further content. You can make certain choices to speed up progression in certain areas, but a lot of things are absolutely required. Don't do this event, well you cannot have a purse until you do. Life Sims don't have main stories. GL doesn't have a main story. You get Sveta, regardless of how, and what you do with her is entirely up to the player. Any forced content on Sveta is mostly because the nature of whatever small storyline does it is to tell the player "Hey, this is here." But Sveta can completely ignore most of it.
At some point someone will come along who wants to advance that side of GL, but it will pretty much be unique reflections, as she is doing things she isn't used to. Right now, the first like 10 times she showers she thinks how weird it is to have a girls body. But that's about as advanced as that side of GL CAN get.
You partially misunderstand me.
I didn't think you should do it totally like Clean Slate.
In Girl Life you are, of course, in the body of a girl, I wouldn't want to change this.
I just though you could take a single aspect of Clean Slate,
i.e. model some similar mechanism for sexual pfereference like in Clean Slagte-
After all,. while in a girls body, you still have a male mind (at least in the m2f starts).
You said that in GL things aren't forced upon Sveta, but that actually isn't correct ... you already have a similar mechanism as I envision, when it comes to clothes ... i.e. some type of clothes are locked away from you, till you have the necessary nlow inhibition value.
In a way that could (hypothetically) be done similar for sexual preference. For example a range from 1-100 like for other attributes ... 0 being female attracted, 50 being bisexual, 100 being male attracted. (or maybe a range from 0-200 with 0 female, 100 bi and 200 male attracted)
If you are female attracted, you can only have sex (or do blow jobs) with males if being inebriated, very horny or being forced.
And vice versa if you are male attracted.
But every sexual activity contrary to your preference would shift the attribute by +1/-1 (or +x/-x) towards the other middle.
Actually, thinking about it, this could even work with a system where the player determines his sexual preferfence from the beginning on ... i.e. the initial value would be 0 if he determines (at the start of the game) that he is female attracted, 50 if bisexual and 100 if male attracted.
So, actually the player could still be very flexible with this system and determine for himself the starting parameters (which isn't possible in this way in Clean Slate, btw., insofar, such a system would actually surpass the system like it is implemented in Clean Slate).
But yes, the drawback would be, of course, that it would take some work to integrate such a mechanism into the game.
And of course it is still your (i.e. the Devs) game, what I wrote is just a suggestion which, at least IMHO, would make the game even better than it already is.
