"Well", Jack thought, "it would only be fair for me to be the first case". Jack not only had a thing for trans people, he also wanted to be one, but, since he was cis, he never felt any need to transition, as the idea of being a woman wierded him out. Now, the virus would rewrite his life to make him become the trans man he always dreamed he would become. Of course, he had to purge his knowledge of the virus as well as the ring, since he would not have the full transgender experience if he could simply change his sex. So he added a few more clauses to his note.
"Partient Zero of the virus will be Jack O' Rieley, owner of the magic wishing ring. The virus will take effect 5 minutes after the wish creating the virus is made"
"Once reality is rewritten, Jack will forget he ever owned the magic ring, until the events of his 35th birthday (tommarow), at which point, it will appear to him alongside a note explainging how it works, but not explaining its origins"
"The ring that reappears before Jack will not allow him to directly transform his body, learn about the trans virus, or manipulate the trans virus in any way"
"Well, this is it old friend" Jack half-jokingly said to his penis.

Since he had 5 minutes, and was rock hard, Jack decided to spend his last five minutes with XY chromasomes jerking off old natural one last time.
Unsiprisingly, Jack's final wank in this reality was literally the best he ever had, his mind still reeling from his ejaculation, he began to feel an odd sensation, like an erection in reverse. His penis was slowly recceding into his body, and he began to feel a twisting feeling in the pit of his stomach as he began to grow a womb, soon after his testicles began to receed, transforming into ovaries as millions of sperm became his ovum. By now his shaft had fully recceded, and his head sealed up and began to grow a hood. Jack had never been more aroused in his life. Then, the flat region that was once his scrotum split open, opening a path to his newly developed womb. It was then that Jack's mind started to get hazy, he began to forget treasured childhood memories of tee ball and boy scouts as they were replaced with memories of another person. A girl named Pauline, who never seemed to fit in and was deeply uncomfortable in her own skin. Jack then began to see his body morph into that of a young girl, whether he was actually regressing or just hallucinating, not even the ring could know. It was at this point that Jack blacked out. When they woke up at 6pm that nigh they were
