I'll have tread carefully relaying this story but....
In my first full time job I was the only male in office of about 20 females (all ages).!
They would often include me in their stories, dare I say at times delight in doing so, and swore that one of the women would blatantly engage in f.........ing - they even went so far as to tell me to watch her when she was standing by another colleague's desk - I just never knew it had a name!
