Hello, here are some ideas :
Try to offer same/equivalent options regardless of sex in interactions/locations (unless biologically impossible of course).
-> This will help give more freedom to players.
New trait : strait, gay/lesbian, bi, pan
-> Guest house events, if guests of compatible orientation (observe, join, send to basement, banish, etc).
New gender : trans women
-> Chance to meet in nightclub, on the streets maybe like the old women event.
New building : sex dungeon
-> Punishment for guests with masochist trait without sending them to basement.
New traits : sadistic
-> Will allow guests to dominate MC and masochist guests in sex dungeon and slaves in basement.
New location : Workers market in the city to hire guests.
-> Will allow a play style lest focused on slaves.
Keep it up !
