There's an entire thread in the How To... forum devoted to issues pertaining to BDSM. Go post this there for a (possibly) better response.

You don't have to read the whole long damn thread to post on it, either. Just do it. Here's the link: http://www.literotica.com/forum/showthread.php?threadid=39661
