Does your wife know and approve of you being on sites like this one? Alot of people can become ( I'm not sure of the right word) unhappy, defensive, feeling like you are cheating on them when they find out about viewing material like this.

If that isn't an issue try reading romance novels to her. Mrs Diver likes hard core stories sometimes but she is always in the mood for a romance novel. Give J.D. Robb or Nora Roberts a try. To make it even more effective get rid of the kids, draw a nice bubble bath and read to her while she is soaking.
