Boyfriend goes on Live sex webcam chats, should it bother me?

[Gina D]

We moved in together about 3 months ago and we both enjoy watching porn and we are well aware of our habits and are comfortable with it. Meaning movies, pictures stories. We dont watch it together all the time (I prefer it that way) but he wont hide it if hes looking at these.
Recently he went on to something called jizz live and he does try to hide it from me. I havent confronted him yet, I'm going to do that later but would like some opinions.
He talks with girls from the other side of the globe so I know he isnt going to meet up with them and I trust him enough not to cheat.
So it bothers me that he tries to hide it and I feel inadequate now and im starting to get a bit distant.
He could be sitting near me and just turns the computer at an angle that I cant see, or so he thinks because I can see the website reflected on the window or his glasses lol!
Anyway, thanks for any opinions =)
