So... well, they spent a lot of time trying to use the wand... and trying to wish their way around the situation... but nothing happened. Nothing. Nothing would get him his dick back... so they decided they had to work around it.
More importantly, they needed to keep their wishes small, for less backfiring.
The first wish for damage control was to create private showers in the boys locker room... they realized that outlawing gym showers would just end up sticky and stinky. The second got him a prostesis so simulate the appearence of maleness... again, not much more than what could've been gotten without a wish, just with some money... so not a dangerous wish.
As the days passed, well, actually it wasn't so bad for Jon, in a weird way. It meant the constant attention of Karyn, bonding with Karyn, needing Karyn to teach him things... again, wishing for these things instantaneously could backfire... and a real intimacy with her. Literally, considering how truly initmate teaching one how to care for and operate one's genitals can be.
Regardless of it all, however... frustration built... and eventually one day, wearing the stone around his neck, Jon... thinking of his new pussy... exclaimed "I WISH I just knew what to DO with this thing!"
And... well... that wasn't good, of course.
Ultimately, what one does with a vagina... if you wanna get primal... is collect sperm and create children. And... well... suddenly, Jon was filled with an overabundence of that knowledge... a NEED...
Not really a need for men, he was still basically attracted to women... but more like, he suddenly felt his biological clock ticking. LOUDLY. A search for a suitable mate and getting pregnant began to overtake him, even though lust had nothing to do with it.
Biological urge. Jon needed to be a mother. Or, rather, he KNEW that.
