"Sometimes" for me. I found I started swearing a lot more after leaving home, since my parents were always sticklers for clean language (well, my mum anyway - I've heard my dad swear a few times when he thinks no one's listening).
Too much, way too much. But I'm trying give up from that habit, since it's quite ridicilous. And my boyfriend doesn't swear at all and I always feel myself stupid and childish, when I swear around him x__x.
But actually Finnish swear words are just beautiful and suits for our language imo.
