Beta Reading and a Challenge

I have two friends that are writing novels.  They're both pretty good as far as I'm concerned.  I've had a little time off and on over the past.. year? or so to help them out and beta read for them, which has been a lot of fun for me.  Hopefully it's been helpful for them.  They write different types of things, but one thing most fiction seems to encompass in some form or another is love/sex.  This can be a hard thing to write about, even if you don't think anyone else will read it.  If you're trying to get published, I imagine the pressure is.. more.

So I'm talking to one of these friends tonight about this topic; writing something that makes you uncomfortable.  She mentioned how the word "folds" in relation to.. relations, made her squeamish.  "Please don't make me use the word "folds" in that manner."  I decided to do it for her.

"he folds down the sheets, inviting her to join him"

"he folds his arms around her waist, snuggling her closer"

"she folds his money into her wallet, a job well done"

She felt dirty.  I felt as though my job was accomplished.  Perhaps I should become a snippet author.  Is there a market for that?
