Boyfriend looking up pornstar.

Would you be offended if you SO looked up a porn star to jerk off too later?My boyfriend watches porn and I hate it but I know you cant stop it so I just let him do it but I looked through his instagram and he looked up a certain pornstar I asked him why and he said "Im pretty sure you know why" Im so fucking hurt and he has a hard time keeping it hard sometimes..Idk what to do.I then said "So you jerk off to her pictures see that's why theres no trust thats so wrong on so many levels" and he said I dont jerk off to her i just wanted to see if I wanted too and I didint" Like yeah SURE!
