Is it normal it hurts when im angry ?

I dont get tantrums and I can control my anger. When im with people which I rarely am because of my inability to proper socialize because of my aspergers syndrome, I never get angry at them or shout. But after I leave the room or at the end of the convo I am angry. But im not controlling it I dont say to myself f*ck that person or that statement. I want to be peacefull but my brain is sending signals of anger. As in orgasms. Not like you would wanna stop them but you cant because of the dopamine. Well its the same with anger just it lasts longer...Is it normal ? And I hate the feeling I need advise to make it go away. I get angry alot lately im off nicotine.
