My husband and I are interested in dabbling around the edges of BDSM to enrich our sex life. I don't see us going to any clubs or anything that serious, and we aren't going to try anything dangerous or painful (don't try this at home means something to us!). Can you give me some tips on how to get started? How we can learn about it; for example, how he can learn to give a good spanking that doesn't involve hitting my tailbone? Of course I'm reading a lot about it, but we need some concrete advice for Step 1, Step 2, etc.
