Here is one if you happen find this interesting. Like i said before these "contracts" are there mainly to help both parties know what other person likes etc (hard and soft limits, safe words etc). I think most people don't really use them, they discuss these things verbally, but writing it down also help you to really think about it.
Writen contracts are often used in bdsm scenes. Not only in the movies. They are mainly there that both parties know what is allowed and what is not.
Didn´t know, thank you for explaining to me, very friendly
