Pervy bf

My boyfriend all the time is calling girls hot if he sees them on tv/vidoes/etc like excessively and last night he was scrolling through fb videos, me sitting by him watching too, and he stopped at one that showed a super hot girl with her huge tits hanging half way outta her shirt playing the guitar and he says "damn she's hot" and just sits there and watches it... i feel like him doing that is disrespectful. Like out of all the videos to watch and he chooses that when I'm right there beside him obviously with no interest to see that. He doesnt even concider my feelings. I feel like it reflects how he would think or act in real life situations. And I didn't get mad or freak out I just let him watch it and said nothing, then after a minute of him still eyes glues to the screen I said goodnight and went to bed. He didn't care. I'm not insecure, I love myself, but him doing that is disrespectful to me and is a HUGE turn off, idk what to do about it. Help?
