I hope there isn't already a thread like that - my search for it wasn't succsessfull

Some days ago a friend came over to watch a basketball-match and as a Student I have to study, sleep and watch TV in the same room.
While we were sitting there my gf came in said hello and then walked to my nightstand and put my two cameras into a drawer.
First my friend said nothing but when she left after a few minutes he laughed and ask why she had to hide the cameras? Of course he could guess but I didn't tell him that we take pictures of her cum covered face :P
but it was quite hot to talk to someone (although we just made some unspecific jokes) about taking some "sexy" pictures.
And then I had a idea for this thread, because

I wonder if your friends/colleagues (or even your family?) know what you are doing?
Do they know you are into facials?
Do they know you take pictures? (if you do?)
And if you are posting pictures do they also know it or have they even seen them?
How did they find out or why did you tell them?

The only one who knows that we are taking pictures of my gfs covered face, is my cousin
and not becuase I told him but because he was using my pc and I forgot delete the wallpaper I used to have at my private PC. -.-
but we never talked about it - he must have seen it, but he didn't even make some jokes (what I propbably would have done if I would be in his postion :P)
