Boo to an absence of sex scenes. I have read plenty of sex scenes that were neither awkward or creepy. I like a good sex scene in a book and hate it when all sex is subtracted. I don't think what you're describing, Anis, is more intense than anything I've read in a variety of mainstream novels.
Read Birdsong and say that. I swear I stopped reading that book when I could hear Sebastian Faulks masturbating with every turn of the page. I know why he made the sex scenes so graphic, but he couldn't make them sound anything other than bad fanfiction.
It had such potential as well.
And George RRRMRMR Martin or whatever the hell is name is. If you find yourself writing a scene where a twelve year old girl gets raped by Genghis Khan, and Ghengis is meant to be the good guy because he went down on her... then just hand yourself into the police, your dangerously disturbed.
Unless you are going to do it with respect, don't even try.
