Is This Normal for a Male Scorpio PDA?

We have been dating for almost 4 months. At first we were both shy even in the department but it balances out well. Our relationship took off really fast. He likes to show Public Display of Affection but I thought Scorpios were secretive about their emotions. He lets everyone know I belong to him and he even gets aggressive with drivers who cut me off on the road lol I feel protected with him but I also hear they are actors and make you feel like the center of their world while cheating their es off. I haven't found any fault in him yet and i'm learning to cook (being a Taurus) and he cleans his plate even if I burned dinner lol I'm a great cook now
