I've been told that during sexual intercourse, you must only use parts of your own body. However, to pleasure us both further, would I be able to use a simple scarf (or other materials such a rope or a hijab) to tie her hands to the bedpost?
*What I mean is would it be haram to use a rope? It is an external object, which I think is haram to use, but I am not sure. I know that oils are allowed, even recommended by the prophet himself in hadiths, but would it be haram to use a rope?
