Yes, because even in the wizarding world, female hygiene items are those things that should not be named, and it is a well-known fact that embarassment is the only possible male reaction to being confronted with a tampon (or its wizarding equivalent, which I'm assuming is what Andy is writing about here).

Seriously, most of my classmates in school were more mature than that whenever a tampon was passed along under the desks to someone who needed it.
