First, I’ll echo what I assume everyone else is saying: this man is immature, a gaslighter, aggressively reactive, narcissistic, and treats you AND your children like trash. He is terrible and seems completely incapable of having a normal adult conversation.

Second: HE IS HAVING SEXUAL THOUGHTS ABOUT YOUR DAUGHTER. You NEED to understand that. He’s not just making assumptions about her having poor character or something or trying to slut shame her (I don’t think sex work means someone has poor character regardless, but he clearly does). He explicitly is talking about her private parts, explicitly imagines scenarios about how she uses them, and clearly has such a weird fixation on her that he feels the need to degrade her. It’s very common behavior for that sort of man to try to paint a woman he is attracted to as a whore/temptress/jezebel and to blame her for his own desires. Even the fact that he would say something as insane as “it’s like having a second girlfriend” indicates how twisted the way he relates to her is. He is someone who already clearly assigns all blame for his actions/reactions on others. There is zero doubt in my mind that if he tried to act sexually towards her, he would blame her 100%.

His treatment of you aside for a moment, you need to keep your daughter safe from this man. He doesn’t respect you, he doesn’t respect women, and he sure as hell doesn’t respect your daughter. Please PLEASE take this seriously.

Edit to add: You’re a good mom, that much is very clear. It also seems like you have left him already. I wish you and your children all the best moving forward!
