New doesn't necessarily mean radical.
If your girlfriend likes "rider", suggest "inverted rider". Your sex is always in bed — try on the kitchen table. I can go on and on and on, but I think we understand each other.
Sex is such a rich thing that turning it into a routine because of your own laziness is just a crime, and there is always a chance that in the search you will stumble upon what you or your partner, it turns out, adore.
