I don't read romance novels. The sex scenes in fantasy stories is as graphic as it gets.
Um... all right, so I'm showing my lack of experience again, but this time it's really OK!
Some romance novels are purely bad plots with racy sex scenes in them, but others are really terrific. Like the one I was talking to Rose about the other night -
Outlander by Diana Gabaldon.
You'd love it since it does involve time travel and Scottish legends and history. It's my all time favorite series! The romance is actually a subplot, but the characters are so well-developed, you start to just love them like real people.
