My (36M) wife (34F) keeps tying my boots after I've told her to keep her hands off of me and that it's degrading

So my wife has this thing where she wants to do all these cliche "wife" moments like you see in anime or a mid. She thinks I'm cute when I'm angry and wants to make me laugh with funny things.<br><br>Well, I just turned 36 this July, so obviously not a young man anymore, but I still make an effort to work out. The problem is my feet. <br><br>When I was a teenager I was in a pretty bad accident and had to have one of my legs and an arm reconstructed. The solidity of my foot makes it hard to wear shoes in general and boots in particular. I've learned to adapt to the best of a situation I can't change, but I've made it very clear to her that it is frustrating and I want to handle my boots how I am best comfortable. I told her it's to avoid the pain it might give me and to keep my leg working. She thinks it's cute because she "remembers when I was sweet and would let her play with my boot". She calls me a tsun and teases me when I get angry. She knows I hate when she does this.<br><br>I told her the reason I don't let her play with my boot laces is because it reminds me I was left handicapped by my accident. She says she doesn't see anything wrong with a man having a little help from his wife, but I see it as her making fun.<br><br>I told her to "stop teasing and keep her hands off me" but she thinks it's cute because I'm "blushing".<br><br>This issue has gone on for months. I've tried saying stop. I've tried explaining how it hurts and makes me feel weak. I've tried ignoring her when she talks to me.<br><br>I'm not sure what else I do other than having a fight with her, but I'm not sure I would win and it's not worth losing her friendship.<br><br>TL;DR My wife wants to tie my boots and all she does is tease me and call me cute, but I think it's degrading and she won't let go of her "joke"
