I find that I swear much more often when in the company of close friends and family members. I think it's a comfort thing, since I know their limits and they know mine and so there's very rarely any misunderstandings between us.
I suppose it's the same online, I tend to type in a very formal manner when on a site such as this, though when in the company of people I've come to know and trust I end up becoming a lot more informal. In regards to role-play itself I'm not opposed to having my characters swear, though only a few of them actually do. Theodric is rather rough around the edges and does it fairly often, whilst my blood elf soldier back in WoW never did as he was conditioned to live and fight for his homeland and very rarely showed his emotions as a result.
