I'm so glad that this vocabulary list exists, so I don't have to write one. If you want to read what regular Finns, whatever that is, write about sex, take a look at the sex forum on vauva.fi. Vauva means baby, but not in the Hey baby way.
If you want to spice up your life with Skype or phone sex in Finnish, Seksipuhelin Marjatta shows you how the magic is done. (And now have a nice day watching all the Kummeli videos on Youtube.)
