Is it appropriate to show your partner the people you have dated or had sex with?

I acquired very indignant with him as a result of a lady we met on the street was being too chatty with him and I used to be on silent indignant mode. Then after she left, he simply stated she was his ex once I did not even ask him and that made me even madder. I advised him I do not wish to know his exes. Interval. And he stated fantastic, however I am nonetheless mad. What’s your opinion?
