Hmm, I'm suddenly reminded of when I was 24 (a couple of years after I felt my first urge to transition), and walked into my doctor's office and asked for a vasectomy. She laughed at me, in front of a medical student who was there (I'm still bearing that grudge like Sméagol bears a ring, dammit) and said come back when you're older - in her defence (pff), she'd just come back from maternity leave, and I had no idea why I wanted the vasectomy, I just always did.
In the end, I got one 10 years ago, just as I was getting together with my wife-to-be (spoiler alert).
Like most of what was going on, I'd aways associated this desire with bad childhood experiences, but now I see it was just another attempt to step outside of being male. So my balls serve little purpose except to feel either nice or awful, depending on how they're handled. I suddenly started shaving it all about a week ago, and that feels like letting go of my connexion with it too.
