Here's how I broached the subject to my husband...
"Honey, I wish you would take the restraints and tie my arms back, bend me over the bed, caress my rear-end tenderly and then give it a good smacking. I like the way my butt tingles afterwards. Then pull my hair - a little - and tell me you love me, and I'll do whatever you want."

It did not pan out the way I had hoped. He's not a sexual person, and he thought it was silly. He also has rheumatoid arthritis in both of his hands, so if he smacks something the wrong way, it's excruciating to him. Long-story-short, he told me to find a bang-buddy the other day (because I am a nymphomaniac and I kind of hate it and we've been together for 17 years, so he claims he has no insecurities when it comes to me just wanting to use another human being to fulfill my "sexual needs"). I probably won't do it. But it would be tempting to find a willing Dom, to use-once-and-destroy.
