I myself am not a fan of wrestling through the labia but I know someone who has been living it out with an intense fetish for years with the aim of making the holes bigger and bigger and incorporating it into D/S sessions again and again. The rings she wears were done by a professional piercer and I think that's the best way to prevent "worse".
However, there are also those who find the thrill of risk in brutality attractive. I just can't imagine how much preparation time he gave her before he pulled the trigger. But I'm sure it's a very special and definitely brutal situation. It wouldn't be my case, but who am I to judge when someone has found a suitable counterpart. Always exciting to see what kind of creative ideas there are.
Yes, exactly this kind of stuff Ive ment.
