Am I overly-sensitive for hating my "father" over this?

My name is Isabella. Growing up, my "father" never acted much like a grown adult... at all. He would always tell me that I was a boy named Bill, and that I had balls. He knew it pissed me off because I knew very fucking well I wasn't a damn boy, and it sure as hell wasn't funny at all to me. It still REALLY pisses me off to this day. I could say that I hate him for it. Mind you, he kept this up from when I was toddler to an 18 year old. My mom told me I was overreacting and it's not that serious.
