I have a family friend who is retired gunny in the Marines. I am moving duty stations and he was to introduce me to an O-3 in the Marines to help me get settled in and help me buy a car and show me around. He is married. I am a Jr enlisted female in the Navy and I was wondering if this would be okay or not. My family friend is not one to care much for rules any more so he is saying of course it's alright.
