Is it bad my boyfriend looks at a lot of even tho.....?

i have been with my boyfriend for 2 years and i am always naked around him and always wanna have with him...he sys he likes how im so ual...but i find him going on sites and he has videos in his cell phone or has pictures in his phone or online.....i feel like i put out more than a usual girlfriend and since i do that i didnt think he would look at as much...should i be worried?
