Dont know if this helps due to me being older. But male friends outside of my marriage, we discuss my husband. We talk about sex. Gawd I talk to my closest friends about sex. Talk about the newest car we want.
I think the older you get, your habits and desires and circle of friends change too. Your interests change. Depending on the age bracket youre in I think is important. She may not be interested in politics, the cost of gas, things like that. It may be more of who has a new movie out or new song, etc. Oh J-Lo having twins!
Just kinda look around you and your network of friends, and go from there!
