First off, let me say, this has been one of the most entertaining threads I have ever read on MR.
My favorite phrases so far, in no particular order, are: "mummy porn", "strawberry shaped wet patch",
"trying to envision my 70 year old mother reading bondage"

I think I'd be embarrassed about the strawberry wet patch incident.
Crawl right under the bench on the bus...
If my MIL knew about the tripe I read...I'd be shunned. Seriously.
(Told my DH if his mother only knew the things I did to him...

..

)
But, as far as my Mum goes.... She got me going on the "Clan of the Cavebear" series, once I reached my early 20's
(ten years ago

) I was too young at the time, when the books were first published.
( I'm born in 80 & still reading Dr. Seuss in 86, I imagine...)
But, both my grandmothers were reading them, at the time, as was my mother.
My Dad's mother complained there was "too much sex" in them....
My Nana (Mum's mum) complained there was NOT ENOUGH.
Soooo, I've had a very liberal upbringing, and Mother was happy as long as I was reading. And now, I enjoy "mummy porn", too!
