It's not all so black and white. Or good and evil. I can understand why your ex's lifestyle would bother you, and I can see how it's a concern for your son. I think it comes down to teaching your son the critical thinking skills necessary to evaluate the different things he comes across in his life. Just because he sees his dad being promiscuous (and let's be clear, he's just 2 years old now, so he doesn't see the world in those terms yet), it doesn't mean he necessarily will become so himself. Maybe the lesson he will learn will be "if I cheat on my wife, I will lose her and have to raise my children in two separate homes, and I know from personal experience how much fun that isn't." He is going to be exposed to many, many things over the course of his life (I can guarantee he will see many more music videos, for example), and he is going to need to know how to deal with them. Life isn't an input - output equation. Just because you're the way you are, the your ex is the way he is, doesn't mean your son will be one or the other.
A friend of mine was divorced when her sons were very young. Her ex and his family are nasty pieces of work. Mean, bitter, vindictive people -- but nothing illegal, and they basically loved the kids, in their own ways. She was so patient about it over the years, and bit her tongue when it came to expressing her opinions to her children. She allowed them complete access to their father and extended family. And eventually, when they got older, they begin to clearly see what their father was like for themselves, and made the decision to see him less. Neither of them turned into their dad.

, and that made you seem a little unbalanced about the whole thing. On the search for casual sex partners while in a relationship...yeah that does make him seem like a UA violation and I would be disgusted but it is what it is. Live your morals with love not with judgement and your son will influenced. After that all you can do is hope for the best.

That's pretty much the only control you have in this situation 

Honestly though, at the end of the day I think the thing that brought me here was a grandma who never stopped praying for her grandchildren. and that is what you can do to fight this. Give it to God and let him fight this battle and int he mean time do your best with your baby and let God use this to grow you into the person he wants you to be.
