I dated a guy who was like this with his son. He and his son would talk about these matters to the last detail. Needless to say, I didn't date him too long.
Some families do this and it just depends on if you are comfortable with this or not. Doesn't sound like you are.
no...its not normal. its not normal one tiny bit.
Hi there. Well, it would certainly be awkward for me. I don't want to hear how my dad has sex nor do I want to tell him about my sex life. Yuck. But before you came into the picture, they probably started this and it is 'normal' for them. I guess some people are more open than others about that stuff.
I don't know how you say--- that subject is off limits. You can try but it probably won't go over well.
So, I'd decide if you can handle this as your boyfriend's normal relationship with his daughter or not and decide if you want to stay or go.
Oh, I DO think you can ask your boyfriend to not discuss YOUR sex life with her. That should be your private business (which would include if he were talking to anyone like a buddy or whatever.) good luck
