OK, this one is just a shorty, working on a lengthy blog entry about something else, but it's something that came up a few times before. We went over that whole stuff about how to tell your partner and all of that, let me try to link:
BDSM and Betrayal
New To BDSM
BDSM and Guilt (which might you help to understand why your spouse is leery)

So in case you are one of the lucky ones who has convinced the wife or the girlfriend to give it a try, you might want to point her in direction of this article (and read it yourself too, you don't expect her to do all the work) just to give her some reassurance and take some of the pressure off!
Good luck to you and enjoy!!!
