I see no reason why she needs to tell you when she is going to be intimate with others you know she is already intimate with. That can just be a given in my books, I don't tell my husband every time I am intimate with Mono. I would be talking about it constantly then and he isn't interested. He doesn't tell me when he is intmate with his boyfriend. Its not my business but I will listen if need be, of course. We especially don't talk about details. The only time anyone gets details is if we all have sex together. Or there is a sexual health concern.
I suggest reading a lot on here more than books. For me real life situations are more beneficial.
