Never had any issue with girls gaming. Anything that I do in a group, I prefer to do in a mixed gender group (never seen any way for "guy-time" to not epic fail). I don't talk any different to people if there's girls around, but I don't say anything online I wouldn't say in person anyway so it doesn't really matter.
Anyone who has issues about losing to a female is an utter wimp in my books.
