Spice and variety is what makes sex become awesome. I've tried some crazy sexual positions and while they were outstanding, when I went back to to the good ol' standards I thought to myself "dang I forget how awesome this felt, it's really really good"
It's like if you eat some gourmet exotic chocolate will that make normal Hershey chocolate taste horrible? Nah, chocolate is chocolate and it is all good. (The analogy started with cars but then I remembered where I was lol)
