How can I tell if my small mango tree is a male or female

by Waterdancer
I planted a mango tree over a year ago and I am not sure if it is a male or female, someone told me it rakes 5 years before it bears any fruit, I don't want it if it is a male & if it is I want to replace it, I got it from a friend, Do I have to graft it? and if I do HOW?
