Hi Faith,

first of all: You cannot tell someone what they can and cannot do. if you tell him not to, he will probably do it behind your back.
The fact that he is showing you these past girls tells you that he is comfortable with you knowing about them, and therefore are over them. If he was all secretive about it, then that would be a problem.
You really shouldn't care, a man who is open about his past relationships is a good thing.

to answer your question it wouldn't be rude to ask him not to, but it would be straight up stupid. making him hide certain aspects of his life is very silly thing to do.
