he revealed something he never mentioned before

So the other night, I was in Florida at my boyfriends house and we had been drinking. My sister and her friend came down to pick me up and drive me back home. We were all talking about sex and freaky shii when all of a sudden he told my sister he wanted to tie my whole body up with ropes and I'm sitting there thinking dayum daddy okay. BUT I just wanna know by some girls on here that has done this before. Does it leaves marks or hurt or anything? 🤔
