I'm not big on needles. Every time I need to get a shot, or give a blood sample, it gives me that icky feeling like listening to nails on a chalkboard. My whole body rebels against this little steel thing entering my veins. Even when I see needles on medical shows and stuff it gives me the heebie-jeebies.
But when I went to an erotic convention, in the BDSM section, i saw a demonstration of a medical staple corset being applied, and it was so beautiful. I don't know if it was the elegance of how it looked, or the care with which the Dom did it, but I felt none of my usual needle aversions, just beauty. Afterwards he offered the viewers a staple in their arm, so they could know how it felt, and I got one. That is how I discovered my needle aversions don't apply to shallow skin penetrations.
And since then I keep getting sidetracked by other things, but a medical staple gun is on my wish list.
