Why does my husband like and naked girls so much!!?

My husband doesn't like to think that I look at other guys. He hates if I say a guy is hott on tv. And he asks sometimes if I want only him forever. But when I ask the same he says, of course! Why do you worry.And one day on tv we saw a show about bikers and there were alot of naked girls. The old kind with lotts of make-up, not really attractive, just their fake . He's from Brazil, so doesn't know about sturgis. I explained to him. Then about 5 min. later asked him to change the channel & he didn't want to.I talked to him about it and said I know it's normal to look. I asked would he like me to bring a girl home. He said if I would like. and he was getting really horney talking about it.I told him we all like , liking too much and bring a girl home could ruin our marriage, he agreed. Then I said let's rent with naked guys, and watch together, or let me bring a cute guy home,he got mad, & agrees its bad to think these things. Why does he get horney so much, should I worry
