"I actually had more sex scenes than any of the other girls. Of course, they're awkward - but the reason that they never loom in my calendar is because a) I have too many of them to fear them and b) they are hugely revealing about my character and important for the series thematically.
"'Girls' isn't exploitative. It put into fashion the idea that a sex scene can also be a moment of character discovery," Williams said.
