Porn...

So yesterday I randomly brought up the topic porn, then made the mistake of asking my bf if he has favorite porn stars. He does watch porn & I will admit at first I was upset about it, but over the past 2 years I've grown to know it's completely normal. But yesterday when I asked him that, he said he doesn't want to answer the question. This turned into a while arguement that I didn't mean to start, but the fact that he didn't want to answer got me upset because then I assume he does. He then told me yes & no. He has certain porn stars that pop up a lot because they're popular, & bc they're good quality hell watch them ? But he said he doesn't go look them up. He then told me it's just all fake (virtual) like they're not even real & that I shouldn't worry about it because I'm hot & real, & they're not & gross. Idk what to think but I don't want to worry about this! HELP please!!!
