My first task for Japan!

I don't know how many of you know about the differences between Japanese spoken by males and by females.
Please see this article for further information: http://en.wikipedia.org/wiki/Onna_kotoba

While watching japanese TV a lot, I have picked up a rather feminine way of speaking which, according to some people, is kind of outdated. Not to say, only few female Japanese of my age speak like that. (So do I sound like a woman in her thirties/fourties? *shudders*)

So my task from a friend who often muses my use of わ (feminine marker) is to find out how awkward people will think my way of speaking is and if it will change if, say, I find a japanese boyfriend who will of course speak male language and might influence me. Apparently, it is common nowadays that girls speak more and more like boys.
But I like my feminine way of speaking. (>__<) It sounds much softer.

Well, we'll see! I'll keep you updated for sure.
