WTF - How to write a sex scene

So a possible editor sent back one of romance manuscripts telling me I need a few "steamy" scenes.

Enter how to pull off the sex scene.

Read a bunch of porn, no I'm just kidding. My imagination is much better than that.

Sit in the living room, working on the scene, figuring out what three items should be included.

boobs?

Butt?

The big deal?

Then figure out how they are going to do it, not the Fifty Shades of Grey do it, but a normal, "romantic" sex scene do it.

Why can't they fade to black like most of the movies? Why is she asking me for details?

Oh FiFty Shades of Grey you ruined it for everyone.

So I start writing the scene, and soon get lost in the moment. Stopping periodically looking around the room.

It is surreal.

Here I am writing a sex scene and both of my boys are sitting and doing their homework. The Great Food Truck Race is playing on the TV, the dog is snoring on her bed. Everything so ordinary, then why am I sweating so much.

I plow into it, wondering,

"Seriously, does that ever really happen?" (Gazing into her luminous eyes, his breath caught at her beauty, gag gag!)

Then I move to, "Wait, I forgot the part where they stripped, how did they end up there from getting out of the car?

Finally, rereading thinking, "Is most of that humanly possible?"

I look up again and my perfectly normal household is continuing on, no one noticing my face is flushed and I am sweating.

Then I go back again over it again, please, not for the pleasure of it, because it is not right.

"Started a story as old as time?" Oh god, that sounds horrible.

"Pausing, he asked, Are you Sure?" Hell, they are already there, have to remove this line.

Crap, she had a white T-shirt in the beginning and now is putting on a black one, is she a quick change artist?

Finally, I get it the way I want it, going in the kitchen for a cool drink of water.

"Mom, are you OK?"

"Sure honey, just working on a few things."

"Why is your face so red? Are you having a hot flash?"

"Yes honey, it is a hot flash."

Then it hits me, they want this because it is good exercise for us women. Reading what I written, made my heartbeat rise, I used my arm muscles fanning my face, several muscles tensed (kegels anyone?) 

That's why we have to include these scenes in our novels, it is for the good of society.

It keeps everyone in shape.
