Should I be concerned

You should be concerned because your boyfriend is a weirdo, not because of yourself.

I thought the same thing

If your boyfriend watches porn occasionally, I wouldn't be too concern. I suspect there are a lot of guys out there who watch porn from time to time, but they generally don't let their girlfriend know about it. There are some couples out there who watch porn together because that is what they both like.. If he watches porn EXCESSIVELY and make no effort to conceal it from you, he's either bold or not too bright.
