forced transformation from man to sissy because my cock is useless

I've always had a very small dick. About 11 cm erect. I've had several women in my life but they all left me because of my small dick, I never managed to give them an orgasm and I was always submissive to my women, especially the last one. When we were a couple, she often tied me up when we had sex. I love it when a woman handcuffs me. She very often asked me to lie on my back and she sat on my face so I could lick her pussy, even in public places! Until one day she asked me to lie on the floor in a public toilet. I obeyed and she sat on my face as usual, except my wife didn't lock the door. a guy heard us and opened the door. He asked my wife if he could watch and my wife and I agreed. When he wanted to cum he asked my wife if she could take it off because he wanted to cum on my face. She acted as if she hadn't heard and a few seconds later, when the guy was about to cum, she stood up to make room for him. My wife watched this stranger cover my face with cum and she loved it. From then on, she changed the way she was around me, and that's how I became a sissy. At first, she first asked me to stop wearing boxer shorts and only wear women's panties. I refused several times but she often insisted that I wear panties when I licked her pussy. one day to surprise her I put one of her panties under my pants and when she asked me to get on the floor to lick her I undressed to show her the surprise! I thought she would be happy but I was wrong. She was angry! That was the day I received my first punishment and she became violent with me. She tells me to go to the side of the table and get on all fours. She looked for handcuffs but she didn't tie my hands like usual. She handcuffed each of my ankles to a leg of the table. In less than 30 seconds I was on all fours with my legs spread. That's when she told me that she was mad at me because I was wearing one of her panties and that's why she was going to punish my balls. It was my first ballbusting session. She kicked me in the balls until I made her several promises. At first I refused but after a quarter of an hour, I had to make her the promises she wanted. I promised her that as soon as she finished slapping my balls, we would go shopping so I could buy my own panties. I promised her that we would go to a sex shop to buy a chastity cage, and that I would obey her all day, no matter what she wanted. we went shopping, chose panties together and bought a metal chastity cage at the sex shop as well as accessories like nipple clamps, a riding crop, a round gag… When we finished our shopping, she asked me to go to the public toilets of the supermarket together and enter a booth that closed with a door. She pulled down my pants and locked my cock in the new cage. Afterwards, I had to get naked. She put all my clothes in her bag. she only left me with panties and my shoes and told me to wait for her here while she went shopping without me. I obviously did what she told me because I couldn't leave the cabin without clothes. She came back after 30 minutes with new clothes for me. She explained to me that my men's clothes were in the car and that if I wanted to get out of the bathroom, my only option was to put on the clothes she had brought me.I looked in the bags she had brought me and there were skirts, a dress, leggings, and only one item of clothing for the top: a fairly short women's jacket in pink leather. I put on the jacket that reached up to my navel. I told him that for the bottom I was choosing leggings because I didn't want to walk around in public in a skirt. She had bought 3, one black, one red with patterns and one light brown. She asked me to wear light brown leggings that hugged my butt and cage a lot. You could see I had a chastity cage under those leggings. We came out of the bathroom and walked to the car in front of everyone. I was trying to hide my cage with my hand and when my wife noticed, she grabbed my hand so I couldn't hide.we went in car and since then I'm a sissy
