Daughter told me about his porn habits

[Removed to protect my identity]<br><br>I (52m) was close with my daughter (23f) and she told me about her sex life with her dad. She told me when we were alone that her dad had a "weird kink" for her. I didn't think much of it until I realized how serious it was. She told me that his favorite porn category was "incest" and he'd ask her to do degrading things to her, which disgusted her. She warned me about his behavior around her.<br><br>I confronted him about it, but he got angry and denied everything. But I could tell he was lying. It was disturbing to me, and I did my best to protect her from his influence.<br><br>I'm just sharing this because I feel grossed out by it myself, and I have no one else to talk to about it except my therapist.
