I'm expecting to play this game in deep and bro I'll suggest you things based on it, like for now I still have some suggestion I'll drop here and on discord too,
They are Supplies for menstrual cycle like pads, tampons, menstrual cup etc and infact integrate one more system if possible like vaginal discharge for females then it will be more realistic and then you can add panty liners too for this. In short add option to buy these supply from store for female or infact if an npc is in relationship with main npc (me) then she can ask me to buy it too. Then s*x in pregnancy should totally depends on many factors like mood, trimester etc, and if consentually npc doesn't want to do s*x then we can't during it, and if we want to anyway then, it will decrease affection maybe even in worst case loose of relationship, infact add a criminal offense system so she can report, do same thing for ovulation day like on risky days or on period npc either won't allow s*x depends on mood fatigue etc factors but she even can but if she didn't then decrease affection etc if it's non consentual, and on risky window she'll suggest to wear protection strongly.
I hope you'll consider these features for future updates can't wait for these features to be implemented in game 🫶🏻
