play partner turned out to have content online and we didnt know

met a single guy through a local app, had a really nice connection over a few weeks, met up, all good, did it again. then a friend of my wifes who is on twitter sent her a clip from a porn site and its him with another couple. like full face on, recognisable, on a tube site. were not anti porn at all but the issue is we werent told. would have changed how we approached the meet, what we said, whether we recorded anything ourselves. is there an expectation that ppl in the LS disclose if they make content... feels like there should be but maybe im old fashioned
