My mom told me it was none of my business who my real father is and I would like to know how to go about looking for him. Like I said I don't even know who he is

Do you know where your birth certificate is? Do you know what hospital you were born in?

On the birth certificate your birth fathers name should be listed.

Is there maybe a reason your mother doesn't want you to find him? How old are you?

She must believe she is protecting you from something

OK-but do you have an other father,like marital or step-father?
