When you start the game you can start the "exhibitionist" origin perk, from there at night start out going topless at the park (no shirt, bra, then no top, eventually you can work your way to being completely nude at the park at night, then walking around in plain daylight stark naked)
I'm not sure, I do however know if you if you started out with the male origin you are prompted with the origin perk a handful of times along with the "should I get pregnant" prompt which basically let's you choose "try to get pregnant" "leave it up to voice" or "avoid pregnancy at all costs" it usually pops up I believe before or after that prompt, now I have also found out that if you look somewhere through the cheat menu you'll see a option "perk menu" that is the other way to unlock perks and every perk you can have is in there im pretty sure, is hard as fk to hit the microscopic ass "+" and "-" sighs though 😂 wouldn't recommend if you have fingers bigger than a toddler's
