Hey, Melpomene.
I chose sterilization as early as I found out it was covered by insurance. 
To address yer questions:
Not a fan of children; never wanted to have any, never wanted to be one, never liked being around them. And never bought the argument that I would like a child if it was my own.
I hate admitting to carelessness, but I went with sterlization because I don’t often practice safe sex or regular, temporary birth control. (No lectures about STDs, please – to me, pregnancy is by far the nastiest STD there is.)
I got pregnant when I was 16 and ignorant, and again when I was 24 and careless. After the second pregnancy, I figured I better take more long-term action. I had no doubts with either pregnancy that I did not want children and that I had no problems other than financial about ending the pregnancy.
I actually was leaning toward thoughts of a sex change before the sterilization. After the sterilization, I was so relieved not to have to worry about my body betraying me anymore that the desire for a sex change just evaporated. I realized that it wasn’t the body as female that bothered me so much: It was the body as female and pregnant against my will that bothered me. Made me a much saner person to be relieved of that fear.
Also, I’ve always been extremely sensitive to the hormones in birth-control pills. No matter what type of pill I tried, I got extremely moody. Given that I’m not particularly calm when I’m not moody, extremely moody is a Very Bad Thing.
When I was 24, as soon as I could after terminating the second pregnancy. (I’m 33 now.)
9 years, going on 10.
I went to the doctor my gynecologist told me would perform the operation. I asked about the different methods he did. He performed various types of tubal ligation. See these sites for info about the different types of tubal ligation:

I didn’t really need a hysterectomy, so he wouldn’t do that. Which I suppose worked out okay, because I don’t have to take hormones nowadays to compensate. However, it does mean that I’m still subject to PMS and menstruation. 
My gynecologist referred me to the local doc who performed sterlizations regularly. She didn’t think he’d go for it, because I was “so young”. Feh.
This was the first voluntary surgery I ever had. Looking back on it, it was pretty standard, procedure-wise: Show up at hospital, answer the same 10 questions for 10 different people, get wheeled in, get knocked out, and wake up in pain.
Now that I’ve been through other surgeries, I can look back and say that I was handled like a piece of meat and I’d like to go back and smack the whole damn group of them upside the head.
Neither the doctor nor any of his staff took the time to explain to me what the surgery would really be like for me as a patient. They explained the procedure, as in what they would do, but not what effects this would have on me. I ended up in a phenomenal amount of pain, so much that I still remember it nearly 10 years later. I posted about it here.
The doctor provided no aftercare whatsoever – they sent me home, and that was it.
I regret that I didn’t know enough to do the proper research. Nowadays, I ask a lot more questions. And I’m much more assertive, rather than falling into that “doctor knows best” mentality.
I regret that I never sent that doctor a letter telling him what a complete wanker he was, and copying the local medical board.
I regret that I didn’t punch out the nurse during the following conversation immediately before surgery:
[Anesthesiologist]Is there any chance you might be pregnant?
[Me]Well, yes, I suppose it’s possible. Why?
[Nurse]Anesthesia is bad for babies.
Argh! I’m there getting a tubal ligation, you twit! If a baby’s health was my primary concern, I probably wouldn’t be doing that.
I regret that I didn’t have the money to pay cash for the procedure so I could pick my own doctor. The surgeries I’ve had where I paid cash and picked my own doctor have consistently been more pleasant and educational than those paid for by insurance. (One notable exception: When I had to have an emergency appendectomy at Seattle’s Providence hospital, I was very impressed from beginning to end. Great folks there.)
I regret and resent that I had to become pregnant a second time before any of my gynecology providers had the courtesy to even mention sterilization as an option. IMO, every form of birth control should be public knowledge and publicly accessible to anyone of breeding age.
…
Whew, I can go on and on. If you’d like more info, e-mail me.
Best wishes.
