Hi. Yoli The EA's Pet Crazy Girl here.
Some time ago one of the other girls in our little "special interest" group (The Kinky Kastration Koven) asked our eunuch friend, Barry, if he ever felt sensations as though his ballsies were still "in the bag." He stated that such sensations very rarely occur nowadays but were fairly frequent during the first few months post-castration.
Anyway, my curiosity was piqued so I typed "phantom pain", hit "Search", and found a wealth of sites dealing with the phenomenom of phantom pain. I found nothing related to phantom balls but there are numerous instances where a man whose peepee has been whacked off experiences sensations of it still being attached, to include pain, erections, arousal, etc, even the sensation of it being there when urinating.
In one case, a man, age 44, lost his peepee to cancer but experienced phantom sensations so real that he often had to look or feel "down there" to see if he really had lost his little chew-toy. According to the data, this went on until he died nearly 40 yrs later.
Do a little 'net research and I think you'll find a wealth of information on the subject.
I have a casual acquaintance, through my church, whose husband, I'm told, underwent partial peepeewhacktomy

some ten or twelve years ago when he was in his late 40s. I've met him a few times, at church, but have never had the nerve (or gall!) to tug him into a corner behind the organ and ask if it's true that HIS organ has been abbreviated.
After all, what would I say to him if he admitted it was true? Well, my friends and lovers here, intact and otherwise, would have no trouble answering the following multiple choice question.
If the nice man told Yoli that he had lost all or part of his peepee Yoli (ever the compassionate girl) would say (Choose one):
A. "I'm so sorry. But YOU are still here and that's what most matters."
B. "I admire your strength and courage. God Bless You!"
C. "I so admire you and your wife for facing this together."
D. "Wow! May I see? What's it like? Show meeeeee!"
If you chose "Deeeeee", you know meeeeee!
