These are not your ordinary flimsy play cuffs--they are durable and won't wear out after a couple of uses. We got them to try, using neckties to tie them to the bed. I always thought there must be a really good reason for neckties! If you haven't tried sex with cuffs, you are missing something very exciting. I would not recommend it with someone you don't trust completely, because you can't get out of these by yourself.
