How should i feel towards my boyfriend when he does this?

My boyfriend and I have been dating for 1 year. We've never ever had a fight or argument and we get along perfectly and love each other a lot. Sometimes, however, I question my feelings for him because he'll say things like he likes it when other girls dress skimpy and revealing and that he's a little disappointed in me cuz i won't do those things. I feel like he would bang some if he got the chance, which makes me sad and unsure whether i trust him. But he always says it with a laugh and i'm just not sure whether he's joking around or not. But it really kind of hurts my feelings because I want to be in love with someone that isn't into that kind of stuff. but I love him SO much, so how can I just look past that and feel unconditional love for him?! I'm afraid to talk to him about it because I don't want him to think I take things too seriously if he was joking....what should i do? any advice?
