After a rocky few months, the wife has decided she wants to try being intimate again, and she has an affinity for 50 shades type books. I got these Under Bed Restraint System - Sportsheets but I have never done this with her in the 10 years we have been married. What are some opinions on the best way to get her into these and comfortable with them? Best to dominate and place her into these somewhat forcefully (with consent of course), or ask her to get into them? Thoughts?
