I'm going reply to the second part of the prompt and say I just hope I can find a lover who's both sexy and into all my favorite kinks. I'd want to try every non-lethal form of BDSM and guro play that strikes our fancy over the years.
If she really wanted - I'd in no way coax her into this, but be willing to support her - it'd be sweet to have her become an armless amputee (unless I find someone who's already armless). While I can also get into eye stuff, quads, and debreasting, I'd eventually end up missing those parts and wanting her to have them again, so in real life I'd never go through with any of it unless medical technology guarantees it can be undone.
