I've read parts of the BOEF...And it did actually address homosexuality in a semi-serious manner which was something that wasn't going to happen in 3rd edition. So technically, you could use the BOEG and have nothing more sexual then that dude dwarf is married to that other dude dwarf.
Personally, even if I have never played Cthulhutech I'd place it into the definite yellow flag territory from what I have heard of it. So you admit to enjoying a game with snuff porn adventures? Yeah, that's not reassuring.
