I do take comfort with much of what has been said though and I will keep plugging away with these even although I find F/f so much easier! Thank you all for this advice!
In my own relatively inexperienced opinion, you write what you feel comfortable with, and as the spirit moves you, reach outside that box. I know in my own limited experience, I've written what I know, and that's school discipline in Texas. All the characters in my stories, published or not center around school, and have either teachers and principals, or parents who were once teachers disciplining teen students or children.
I have some ideas for M/F stories and one theme in mind for a F/M story, or at least part of one. We'll see fi I can actually make it work, and see if it's something someone besides me enjoys.
