Imo, if you are not in a hurry, wait a bit.

I knew I wanted one since about your age, I waited about 4 years until I realized that nothing is changing and I went ahead.

But I’m glad I waited because I now feel very at peace with it and I don’t feel the need to explain it to others.

When my family said that I will change my mind I just ignored them because it felt so meaningless when I already know I wanted this for so many years.

Just remember that it is mostly permanent, there is no guarantee that you can reverse it.

Good luck!
