If you're asking when did I, I haven't yet, I'm only 15! If your asking when one should get married, I'd say after they're done with college, and know who they want to marry. Around 26-30 is a good age I guess.
I believe one can get married when he or she feels that they are ready. You can get married at the age of 18 or you can get married at 25. You should know that marriage is a big commitment and is nothing to be taken lightly.
