I have several rules when it comes to writing. Rule 2 is When you think you're about to go over the cliff - go.
But when it comes to sex scenes I've had some issues with scenes that were either too bland or way over the cliff. How do you handle these scenes.
Another member of my writer's group says that one sex scene per book is the maximum.
Reading through your advice, I think I'll keep any sex scene light and "off camera" as much as possible. I agree with Dana's point that these scenes can interrupt the action and in a thriller action is what the reader is looking for.
I believe you have to be comfortable with what you're writing, or the awkwardness will show, whether the details are few or many. Personally, when reading, I skip over detailed descriptions of the mechanics or even the emotions of the deed. I feel like I'm standing outside in the flower bed peeking through the window. A bedroom door closing is enough for me! But, then, I write humorous mysteries and get a lot of mileage out of the mating dance. The teasing, don't you know, can be hilarious. However, if the situation warrants it and the spirit moves you, let 'er rip.
