Lots of great advice here. My 2 cents....

Find a kinky toy store, go together to buy a book or two. Browse the selection and talk about them. Wander over to the flogger display, look at the variety.... leather, deerskin, suede, rubber..... Compare the leather restraints to the rope that is in stock.... Get ideas, share reactions and feelings.

Find some kinky classes, go to one together. A great way to get ideas and confidence in one fell swoop.

Most of all, play safe and have fun!
