In the preceding version (not the beta, which I skipped) I remember seeing a scene with the (female) MC, Steph and her girlfriend. I've replayed from the start and I haven't got that scene. Did I make the wrong choice somewhere?
Sounds like, but it's pretty simple, when you go out on the map, there's always a reason for it (except the last time), and the mc talks about that before leaving the house, so whatever the reason is, do that last, so you won't miss anything.
There's also one "choice" with 3 options you can potentially mess up, but it's pretty simple, and there's even a joke answer that works, so 2 of 3 answers will get you forward with her.
Edit: in regards to dick size: mc is already bigger than average, but I like to keep it in a realistic realm, so there won't be any horse-sized schlongs.
