Though I find your scenario a little confusing as to what it is you seek, I believe you want to play a woman, who has been somehow transformed to a man> right? LOL at any rate, I love the post apocolyptic era scenario, and can not only play a man, but am one as well *hehe*, though I have been known to play either gender and carry it off.
Please feel free to read some of my posts, my Os & Os, and let me know if you think we could be partners, I will do the same with your works to be sure out styles can mesh.
