Whats wrong with my hormones?

I am a male in my mid twentys. I have no problem with getting women. I make friends easily. Money has never been an issue as i work hard. My family are great. Yet i have zero emotions. Never happy or sad. Never angry. Just me all the time. I recently lost a close member of family and throughout the years witnessed some terrible things. However i never care or get upset. I literally have no emotion. I heard it could be a real medical condition. Any one have any ideas. And no im not mad. I have never hurt anyone. Its just me.
