Not sure but nipple piercings and clit piercing can make you more sensitive. I don't know about cuts tho
Idk if it's too far fetch but I think it's to built pleasure faster.
Ex. in bdsm when the person doesn't have a high tolerance for pain they do things that hurt + smth that feels good (spanking + vibrator). So if he plays with his nipples while theyre hurt and then stimulate him in a pleasurable way at the same time, he'll get used to it faster and learn to feel good w pain too
OHHH THAT MAKES SENSE thank you lil bro
What the hell is cutting someone's nipples do?? I'm so confused
