I think Joe's wording might work for me.
To me, one of the keys to the "sex moves" is that it's a two-way thing. In AW proper, the way I interpret it anyway, sex moves kick in when two (or, I suppose, potentially more) people have consensual sex with each other. I wouldn't have them kick in in the case of rape, for example.
So, based on this interpretation, I'm currently figuring that I want any "replacement" of sex moves to similarly be a mutual thing. Thus my idea of genuine communication that is accepted. I, as a ghost, can off some kind of honest message to someone still living, but I can't MAKE the person accept that message.
