I don't know if we're still on the role-play issue here,but I think the main problem men have with role-play is that it is important to their ego that THEY are the one who please their wife. If they're playing a role, then they aren't really themselves. I've managed to get around this a bit with my H by telling him I only imagine him in roles that reflect aspects of his true personality. For instance, my H is a crab so the strict teacher who puts up with no nonsense would be a natural fit. He's also very funny and wisecracking so some sort of burlesque scene would also work.
