Thinking of freezing sperm + getting a vasectomy for total peace of mind. Am I making the right choice here?

Ok, so here is the deal. Ever since I (29M) became sexually active in my early teens, I had trouble trusting birth control. I personally know too many cases of people where BC failed and resulted in kids. Even though I had therapy to combat this, I can't seem to ever fully relax while having sex, no matter if I use a condom or the lady has an UID (or both).

Because I don't want kids, I am thinking of freezing my sperm and getting a vasectomy to never have to worry about this again. The reason for freezing is my age. I'm currently 29 and even though I'm certain that I don't want kids, there is a minuscule possibility that I somehow change my mind in 10+ years because you just never know how life unfolds. I see it purely as a backup plan. Money isn't a problem here, by the way. I can afford yearly sperm storage, the vasectomy and a possible IVF/ICSI treatments in the future.

The thought of never having to worry about BC or having kids sounds sooo freeing to me. I actually light up inside when thinking about it. But it's a very big step for me, as someone who is very risk-averse and thinks everything through over and over... Perhaps I should just bite the bullet and go for it. I've been thinking about this for years already.

Curious to hear about you guys perspectives. Did any of you take the same or a similar route?
