What age do you think it's okay to have a promise ring with you SO?

Danielle • I`m 17 years old.. I enjoy Art, Food & Jeeps. Want to be an O.T. one day. I`m super in love with my boyfriend Michael.❤️
I'm 17, dating my boyfriend for two years. Do you think I'm too young to have a promise ring with him? I mean people have kids younger than me.. I don't want anything like that I just want that certain commitment with him!
