Its a legitimate question . . .
I believe what Hootie and Redhotchio (a hard name to live up to!)said are excellent examples of actions to take.
Although maybe its just the detail the girls go into that phases you?
Its my understanding that women can be somewhat more graphic in their descriptions with their friends than we guys are.
Keep in mind also, that "loose" is a value driven word and presupposes that they share your view of what behaviors are appropriate or not. They are under no such obligation.
In fact they could find your dismay or your judgemental stance to be equally distasteful and an example of intolerance of other people's preference for engaging in whatever behavior THEY find appropriate that isn't hurting anyone else.
You would find a harsh response from me if you sought to modify my behavior to conform with YOUR world view.
Take good care
