People undertake a tonne of risky activities I'd personally never touch with a barge pole. Base jumping, cave diving, swimming with sharks... In each case you're relying on someone else to set it up safely enough so you don't end up dead.
Therefore if it's truly consensual I don't have a problem with what people get up to in their own time.
Porn often takes things to the dangerous / painful extremes and this is a huge issue. But I don't think it means we should make extreme sexual practices illegal. The issue we should be tackling is the normalisation of these extreme practices and the portrayal of them in mass porn.
I don't think it's helpful to insinuate that those who genuinely enjoy it are defective and make vaguely threatening comments about their partner killing them. That's beyond the pale.
And FWIW, as a younger woman I've never once come across a man who expects to have anal sex, expects me to be fully shaved, or who thinks choking is a normal part of sex. I think there's a touch of dramatisation happening here.
