Am i too young for a hysterectomy?

That's not a good idea. There's a reason why tubal ligation is a method of sterilization but not hysterectomy. It's a much more major surgery and comes with a lot more complications. No ethical doctor would agree to a hysterectomy just for the purpose of sterilization. in any case, the least invasive surgery of all is a vasectomy. A lot fewer complications, too. That's the surgery that should be taking place. Tell John you went through all the pain and difficulty and strain of two pregnancies and childbirth. He can go through a 10 minute procedure under anesthesia. It's his turn to take one for the team.
