Well. if the kid found out about your CDing (assuming he doesn;t know) you wouldnt want him to make a big fuss about it, would you?
Looking at such things, which are readily available, seems quite natural to me.
He will get over it. I did after I first discovered internet porn in my 50s....
Would probably keep it to myself too, unless the spouse is not hysterical...If I told my Ex anything like that, we would both work ourselves up into a frenzy.
Don't think it is a big deal -- at least if there is no confrontation.
Just an idle thought -- what if you found he was into cd?
