Violence arouses me ?

I had a wonderful childhood. Wasn't abused or anything or seen anything ****** up. However, I noticed since a youngster I always got aroused by violence or simply seeing a predatorial animal dominating prey or someone getting demolished in a fight. I ended up watching videos as a teen watching people get beheaded and even masturbated to a female being beheaded. Women I date always ask me why am I so dominant but they tend to love it and feel extremely comfortable around me. Is this a bad sign or is this me as a man coming to my true instincts and ignoring social programming because we are originally hunters and men of war and violence is literally a natural thing.
