Porn while LDR!!!!

My boyfriend and I are LDR and he texted me one night saying “hey baby wyd?” I said “Hey love Im watching porn” and he texted saying back “stop watching it” obviously I said why and he said just cuz. And I said okay I will. So I stopped watching it.

So the next day, I text him saying wyd? He said watching porn. I tell him what he told me which was “stop watching it” and he says I can’t I can I can’t.....

Is this wrong in a way? Why would he tell me this and go do it?? Or any other responses?
