Cute but worthless
Whatever you could say about the boy, he definitely was cute. If he didn't have a girlfriend, if she hadn't had a boyfriend she could have considere shagging him.
But then again… his disposition wasn't good either. He was temperamental, easily offended and disliked Slytherins more than anything. And she was a Slytherin. The only ways for her to ever shag him was or by force or by using Polyjuice Potion.
Maybe it was worth it, maybe it wasn't.
But when tempted she moved into position and launched an attack on his crotch with her knee. It felt so good!
