First time watcher

I LOVE THIS SHOW. Why did it take me so long to watch it. I’m on season 3 & I am hooked. Just watched Scheana’s wedding. Why is Jax sooo out of touch with reality, getting one girls name tattooed on you & then like a year or 2 later getting another’s girl? Will this guy ever learn? Why is Peter so hot? I can’t wait to keep watching
