tl:dr
Getting a vasectomy in early Jan'16. I have no kids yet, but preserved a few samples at a cryo facility just in case.

Body
I realize there will be a ton of members disagreeing with me, this is my view of all this and how I'm controlling my future.
I made the decision to get a vasectomy in early '16. I looked up a cryo storage facility and stored a few samples of semen the last couple months. The doctor was hesitant when she learned why I'm storing if I"m a perfectly healthy male. I'm paying for a service, my reasons don't matter but I told her flat out that I'm preventing myself from being trapped by a woman. Her audacity to ask me what my girl thought about this decision and that she needs to be okay with it since it's both our decisions. I almost flipped out, but kept my cool. I simply replied with this : "Tell me, when a woman gets pregnant and the guy doesn't want to be a father, is it okay for the guy to force the girl to get an abortion?". Her response: "Of course not, it's her body and her choice". I blankly stared her in the face with a smirk for about 10s. When I realized this intelligent doctor didn't get what I was after, I simply said: "Well, this is my body. You said xxx for the storage correct?". Nothing after that. It felt good to throw that in her face because clearly she thinks when a man makes a decision about "babies" it's both parties decision but when a woman wants a kid, it's only hers. Jerked to some porn and left.

Why am I doing this?
Here is my plan for the future. I don't honestly know if I would want kids. I don't care if I'm 40, 50 or 60. If I decide one day that I want my DNA to run around then I'll do it. Here's how though. It won't be with a partner like a wife or LTR. Before I made this decision, I thought hard and promised myself, if I do this I swear that I will not have a kid with a wife(not likely, been there) or a gf. Ever. The likely-hood of being divorce raped (common law raped whatever) is very high. I will be stuck. So, working on my career I will probably have a good amount of money one day.

I will pay for a surrogate. It will be a legal contract, the kid will legally be mine by law. I'll get a nice young healthy 19-21 surrogate to carry it. I'll pay her hospital bills etc but when the time comes that kid will be mine and mine only. i don't care if the kid wants to know its mother one day, what I care about is its mine. Nobody can extort me for child support or anything. I'll be wealthy enough to pay for a sitter or live in nanny. i don't care if it's expensive. Doing the math of paying child support with my salary right now i'll end up paying over 225k over 19yrs. A surrogate will be way less than that. If a live in nanny is not the option, I'll figure out a way. But whatever happens, the kid will be mine.

This might be controversial thinking or "going too far". Like I said, this is my plan and my choice. I refuse to become a statistic. All relationships end in no condom sex because why would you not. Girl goes on birth control yadda yadda and boom, like two friends already, surprise baby. I'm fighting against it.

Lessons
No lessons really. Just an insight of what you can do as a man to take back control of your life if you are the kind that likes LTRs and not always worry about condoms and if she's not lying etc.

Bonus points if you don't tell your next LTR you're snipped. When she gets pregnant you calmly get another sperm count test done and show her the results. The power gratification you'll feel when you kick her out will be priceless.

I'm interested in opinions. I made up my mind but I like to listen to various perspectives.
