Is it normal that my cockatiel always want to be with me all the time?

Hi everyone. I have a two and a half year old male cockatiel. He was raised by hand when I bought him. He is active but he ALWAYS want to be on me or close to me all the time. I need to put him in his cage when I am eating because he always try to climb on legs to be with me.

Is it a normal behavior? Is there something I should do?
