Is it normal to never have wet dreams?

I'm an 18 year old dude from NY, I love sex and I love spanking it. But, in all my dreams I have ever had, I have never came. I have had very few wet dreams, mostly very weird dreams that usually end with me dying in some way or another, but all the dreams where i'm close to having sex, something always stops me. I could about to be putting it inside the hottest pornstar only for someone or something popping up stopping me and then waking up. Why can't I just have a good old fashion wet dream?
