Husband stitch

Does anyone know anything about the “husband stitch”? It’s an extra stitch that the doctor puts after birth if you tear and it is done without the mother consent. They do it to make sex better for your husband after you have a baby by tightening your vagina more.... Someone mentioned it in another group and i googled it and apparently it’s a real thing. It’s done without the mother knowing and without consent. Info anyone?? I made the mistake of googling it and now i’m scared of it happening.
