Am I too old to start... gymnastics as a male? (Read more for what I mean)?

-I've been wanting to learn to do back hand springs, flips, being more flexible, stuff of that nature. I'm not looking to go competitive, just some that I may enjoy and have fun staying in shape. I'm 18 years old. If I'm not too old, what exactly should I do to learn? Should I go somewhere for gymnastics?
