How long should a sex scene be in a book?

Guess you can tell I'm back to writing. All true, but I'm still reading my 2 - 5 books a week also. Well this novel I'm reading now--Nameless Book--has a threesome that, I swear, takes up 3 chapters. I kid you not. After reading all that rubbing, and kissing and **********and********* for doggone near 30 pages, I was exhausted just like the characters.

And don't get me wrong, it wasn't that the writing wasn't up to par. It was. I just wondered if it was overkill and kinda of pushing the envelope to let the menage-a-trois become the plot versus the action/adventure plot it began with. Here I am ready for the next sex session while forgetting the reason the book was written in the first place.

So, how long (minutes reading or pages) do you think a sex scene should be. Would 30 pages be too long for the same characters? I would love to hear from you.

Hello World!

Wow, folks, it's been a minute since you've heard from me. I was hit hard, hard, hard by the death of my number one supporter and encourager--my mother--in May. My writing muse tactfully decided to go into mourning with me and I must tell you, I've written barely a conherent sentence since that time. But then this past weekend....something just "clicked."

Seriously. I felt an easing of grief and lightness to my physical being. And let me tell you, delicately, the activities in the wee hours of the morning were....off the chain! So as my spirits lift, my writing will return. And I'm in the middle of some very "interesting" ones. Stay tuned and strap on your seatbelt. Payback, Inc. is on its way.....
