I Enjoy Being A Girl wasn’t inspired by the title of a song, rather a song title came to mind as a good title for the story once it was written. The idea of an alien entity taking over Wyn’s body and changing her personality as well as her eating habits and choices of clothes came slightly out of the blue. The paragraph in which The Doctor declares that his TARDIS is a Backstreet Boys Free Zone was always in my mind as something of the final straw. Having Mel as the one who could help Wyn choose some more appropriate feminine clothing, make up and hair is not as preposterous as it sounds. Mel’s clothes seem over the top by modern standards, but they were fashionable in the flamboyant mid-1980s, and Bonnie Langford now is a very fashionable and attractive woman for her age. A bit of an interlude with Sabalom Glitz is always worth a paragraph or two, anyway.

But much of the rest of the story is serious in its nature. Changing clothes and hair is one thing. But anorexia is another. The Doctor’s feeling of futility about that situation is one which many parents must recognize. Added to that, his feeling of letting Jo down by not being able to look after Wyn makes him a concerned man by the time he decides to get to the bottom of it.

I had intended for The Doctor to be quite severe with the entity, Stella, making her leave Wyn’s body and die. But that would have been too dark for the story which had some comic moment. The idea of growing her a clone body and her mind being regressed to a baby so that she gets to start again came to mind next. It HAS been done before, of course. The Ninth Doctor did the same for Margaret Slitheen in Boomtown. So it is in keeping with The Doctor’s philosophy of life.

Giving the baby to Jo to look after raised some eyebrows on the basis that Jo was a bit too old to start again at parenting. But most people thought it was a nice idea. And after all, Wyn was right. The baby Stella WAS her sister, sort of, with her DNA.

The title song, of course, isn’t at ALL like Wyn, the tomboy who isn’t into men.

I'm a girl, and by me that's only great!
I am proud that my silhouette is curvy,
That I walk with a sweet and girlish gait
With my hips kind of swivelly and swervy.

I adore being dressed in something frilly
When my date comes to get me at my place.
Out I go with my Joe or John or Billy,
Like a filly who is ready for the race!

When I have a brand new hairdo
With my eyelashes all in curl,
I float as the clouds on air do,
I enjoy being a girl!

When men say I'm cute and funny
And my teeth aren't teeth, but pearl,
I just lap it up like honey
I enjoy being a girl!

I flip when a fellow sends me flowers,
I drool over dresses made of lace,
I talk on the telephone for hours
With a pound and a half of cream upon my face!

I'm strictly a female female
And my future I hope will be
In the home of a brave and free male
Who'll enjoy being a guy having a girl... like... me.

When men say I'm sweet as candy
As around in a dance we whirl,
It goes to my head like brandy,
I enjoy being a girl!

When someone with eyes that smoulder
Says he loves ev'ry silken curl
That falls on my iv'ry shoulder,
I enjoy being a girl!

When I hear the compliment'ry whistle
That greets my bikini by the sea,
I turn and I glower and I bristle,
But I happy to know the whistle's meant for me!

I'm strictly a female female
And my future I hope will be
In the home of a brave and free male
Who'll enjoy being a guy having a girl... like... me.
