Boyfriend troubles! HELP ASAP

Okay so me and my boyfriend have been together for about 4 months and he has told me all about his past relationships and just his last in general. I was surprised lol he did date a lot of girls and basically was a little hoe. So, today we were just hanging out casually and I mention how I want to join softball, he then tells me "you should, you have the body for it. And the girls at my school are all really thick and they play softball too" and I guess he saw that I was looking at him like wtf because he then told me how he would notice them before but I just think he's trying to cover it up since I gave him a look. Anyways that's one thing that bothered me but then the other thing is while we were driving to this restaurant he starts talking about this actress he thinks is cute and starts talking about her in such a weird way "she's so damn fine" "she's a milf" "she's hot as fuck" and I don't know it just made me feel uncomfortable because I don't talk about guys like that around him. GIRLS!! Am I overreacting or do I have a reason to be mad?!
