I want to try playing and trying to stay male and masculine as possible for as long as possible.
The problem is that, I actually would want to eventually get corrupted into being female anyways.
But currently I dont think the game will sufficiently corrupt your character to prevent you from staying near 100 masculinity if you really try.
I could be wrong. I know people try and spike your drinks etc. But you can always just use points to get around it.
Maybe mods would help?
This is my playstyle as well, and I do kinda agree with what you say.
If you play well, and save your action points, you can get out of most things.
If you are up for adding mods, they do help (there's one where Alexia forces you to go to the bar and hand around, which helps put a fully reluctant character in situations where they can fail some willpower checks, etc). But I think it might be nice to have an "unfair" difficulty, maybe?
Easiest way to do that would be to either disable AP entirely, or to have much harsher requirements for AP gain. Maybe if you don't get enough sex, your max AP starts to drop, until you can't have any at all?
It'd also be cool to have increased masculine difficulty imposed by masculine choices or actions. Get a bar girl pregnant - maybe she tries to give you a breeder - or maybe her dad works at the nanobot factory, and you get blacklisted for contraceptive bots, etc.
