There are so many things to appreciate about this scene.
a) Ron and Harry having brotp moments (”do your fly by hand” hilarious!)
b) “Unwrap it up here, it’s not for my mother’s eyes”: Ron, could you be more adorable?
c) Ron is giving this book to Harry even though he knows that it will more than likely be used in reference to Ginny (so much for crazy, overprotective big brother Ron!)
d) This basically explodes the notion of Ron being suave and sexually experienced. The poor guy is obviously clueless.
e) It reinforces the idea that he wanted to get rid of Lavender, but was too inexperienced to know how.
f) “I would’ve known how to get going with…” (Even Harry knows who that ellipses belongs to!)
g) The greatest “wand innuendo” in the entire series!! The joke works on so many levels…first you get the picture of poor Ron trying to cast a complicated charm and not quite getting the wand movements correct (flick and swish), and then you get the notion that, despite what most 17 year old boys think, you have to have more than good “wand work” to satisfy a woman.
