this was great, I loved how Arthur figured out he didn't just love Merlin because he was a girl or a guy but because he was Merlin :3

soooo good!

I don't usually like female Merlin stories. And I usually prefer to stay away from slash too.
I could've done without the intense stuff, but other than that, this story had me enthralled. It was just something about it, the humour, friendship, and just the fact that ARTHUR was falling in love with MERLIN without even knowing it!
I like the way you portrayed Mel. Sure, she's still Merlin, but she's also a little different. You incorporated Merlin's personality into it, but also a little more emotional, (what with all those horomones!) and all that.
I was immensely curious to see as to how Mel would somehow reveal that he was Merlin. I'm glad Arthur wasn't so much of a prat to literally ditch Merlin in the middle of their quest.
Also, I like the romance. I don't ship Arthur and Merlin, but for this story I did. That is an accomplishment within itself.
Plus, I like how Arthur still loved Merlin even after he had changed back to his proper gender.
All in all, a good story. Good job!

Perverse smirk?
Yes.

omg so awesome

Fantastic ending. Yay! It's done. Read the first half of this story when you first wrote it. Finally found it again to finish reading.

Oh he would be drop dead gorgeous as a woman, that's for sure.

Personally I could've done without the sex scenes, but the rest of this was hilarious. Only Merlin could get himself in such a ridiculous situation. You did really well writing his thoughts.

another suggestion, at the end of your story you may want to add a line break or at least hit enter a few times to separate your author's note from the story.

! Dang! They could of had awesome babies!

! Oh, Gaius seems to always be there at awkward moments!

! Gwen's pretty smart!

! Lol misunderstandings! XD Arthur!

Ahahaha! Lol Merlin! You could always stay like this! I mean that witch is pretty creepy...is it really worth the risk?

So so good, this fic was so good.
I read some female!merlin fic but I find it OOC because merlin is a man and I prefer things like that.
But this story is completely different because merlin is still a man but he was due to a spell in a female body and it is far more funny, especialy when Arthur arrived and was attracted by Merlin in this body.
I love all the moments between Arthur and Mel, it was funny because Arthur didn't know and merlin was confused to feel like that about the prince.
Their first time before the encounter with the sorcerer was so funny because Arthur wants to test this body before Merlin become a man again. But Fortenulety he loves Merlin like he is, a man and their second time was perfect.

Very amusing, I genuinely did not expect the gender bending from the summary. Amusing. Loved it actually.
