My parents -- well, they haven't had sex in twenty years (I know, because ym Dad complains about it, often!) My mother is a very unhappy person who was truly abused by her parents; whiel she was cool with me growing up, she hasn't aged well. So no, they have no clue. My mother would go ballistic; Dad wouldn;t know what to think.

My wife's parents already want to shoot me (after 22 years, they still expect us to divorce at any minute!)

Parents aren't the problem -- kids are. Some examples:

I walk in to find my 9yo daughter rubbing the back of her Barbie with her mother's favorite dildo. "I'm giving her a massage!" the girl said as the toy buzzed in her hands. Eeeek!

My two older, teenage daughters know Mom and Dad do "weird stuff", and ignore us, except for a few sarcastic comments: "Do I need to put extra pillows on Mom's chair?"

Sigh. Parents really shouldn't have hobbies.
