I actually didn't watch porn back when I was dating... I watched the occasional risque movie but not all out porn... My male friends know I watch porn - not specifically what kind but they give no shits.
one of them however, does know. We often have long and involved conversations about sex and porn and any other topic under the sun because we have no judgements toward each other. He finds the whole pegging idea a bit strange but not disgusted or anything.
We've both kind of have this 'live and let live - whatever floats yo boat'(within reason of not harming other people) philosophy.
