Am I (F24) overreacting to my boyfriend's (M33) response to me watching porn?

**Edit:** I changed the age numbers in the post title because I forgot my age.<br><br><br>I (F24) said to my boyfriend (M33) that I'd be interested in watching porn together, but he said that I should watch it alone so that I could tell him what I prefer. What he didn't know is that I've been watching porn for years. I'm pretty sure that the only thing that he doesn't know about is anal, but I'm not sure of that. (I've never actually had anal, it just seems like something that I would like.) I want to ask him if he knows the true reason why he asked me to watch porn alone, but I don't know how he'll react. I don't really want to know the answer to this, but I want to leave all avenues open just in case. I don't want to bring up why I'm asking him in case he doesn't know. If he answers yes it will confirm my suspicion, but if he answers no I will know that the real answer is yes. I want to know if I'm overreacting or should I bring this up with him? [ Edit: ] I should add that we have been together for 2 years.
