@Vox: I think that's actually pretty true. At least for me. It's not like I didn't read smut in German before (I did before I started reading English fanfiction) but I got to know the words used in smut through English fanfiction so I naturally associate the words with those connotations.
Yes, do a study about that. Good idea.
*nodding along* Yep, I think so too :)
Luckily, I can still read fanfictions in German though it's a really ... odd feeling xD But yeah, English is pretty much my fanfiction language. Though I always liked how English sounds anyway. It's my favorite language I think ^^
