Husband friends with exes

Would it bother you if your husband was still friends with almost all of his exes? One of them he use to talk to about him and her sex life when you and him were dating? They never had sex, just made out, but he tells him about his and your staff x life and she tells him about hers. They don't anymore, but did. She is also known for cheating BIG time! He hasn't ever done anything but talk to her like that and watch porn, but he still talks to her even though you've asked him not to. You're ok with his other exes just not her, but he doesn't care. Would it bother you?
