Weird kink..?

So my SO and I have been playing around with our kinks lately, I use to hate porn but one day he asked to watch it while we have sex and it just went from there. I find it such a turn on when he looks at other women having sex while we have sex, I like it when he talks about what he'd do to them and if they are hot. Weve even talked dirty during sex about threesums (even though we both agree we would never do one) I dont know.. is this normal? I just get so turned on hearing what he has to say about the porn we are watching. Is there anyone else like this?
