Depends on what I'm in the mood for, I like both clean and steamy. Character development is more important.
But I do have a few things I don't want such as 'anal'. It's jsut not sexy.
Most books have lots of lead up and flirty stuff which I like more than the sex in the book. Most sexy book only have two or three actual full intercourse scenes.
I don't want the words 'pu**y' or cum when I read a romance. I don't mind the acts, just not those two words. Romance is about the fantasy and to me that's not sexy. Maybe someone finds it sexy. Not me.
I don't mind a little kink. I don't mind a little down and dirty.
I don't want random sex in the book but sex with the people who are involved.
Sex between people who are into each other is sexy. Sex with strangers is just sad.
But that's me.
