Is there a word or a community for a kink where you like to be held at knife point or be scraped with sharp objects during sex?
My ex told me during our relationship that she has a fantasy of being threatened with a knife/having a knife to her throat during sex, but hasn't been able to fulfill it due to her not feeling safe, but after we broke up, lost contact, became friends after a while and now just have sex occasionally, she wanted to fulfill that fantasy. I figured out a way of moving the knife where I can safely scrape her skin and throat and "threaten" her without hurting her significantly or leaving cuts or bruises. We did it last weekend and she was thrilled.
She wants to do it more often, and I just wanna know if there is a community where I can learn how to do it safer, or a key word to search up to research techniques?
