Can't say that anymore. This past weekend I wrote my first second person/present tense POV piece and I'm very happy with the way it turned out. http://xmen.adult-fanfiction.org/story.php?no=600090320
I thought it would feel awkward, but once I got started I fell right into it. I even got an unqualified positive review from one of my best concrit readers.
So now, I'll have to find the next thing I haven't done...Hmm...
