One thing I was always kind of curious about was how aware characters would be of their sex move. Did anyone know?
It doesn't seem to be explicitly spelled out anywhere (lots of things don't...looks like wiggle room for the gaming group). I think that...If your character knows what they are, and they're NOT a virgin, then it seems sensible that they're pretty aware of any obvious effects of it.
...And if they don't know what they are, then they clearly don't.
There are a lot of these sorts of holes that might be profitably filled in one way by one gaming group and another by another: are monsters secret or does the world know they exist and hunt them? or not hunt them if they behave within limits (a la
Anita Blake)? if monsters are secret, do all monsters know about other monsters...or is a vampire not going to know much more about werewolves than horror novels say about them?
I've been listening to the podcasts of Monsterhearts games at The Walking Eye
. Much hilarity. (They also raise some interesting questions)
