Is there such a thing as being too straightforward? Too honest? Expressing your opinion so bluntly that you spare no thought for how it may sound to the person you're talking to?
You may well get this type of feedback from your partner, who will tell you things so straightforwardly, honestly, and bluntly that it may hurt your feelings. Not that it will stop you from a smart-ass response. And this is the nature of your relationship. You egg each other on, driving each other to excess, escalating the situation for good or for ill, with no holds barred. Your conversations become a contest to see who can say the most shocking thing, who can raise the most eyebrows. The energy between you two is best diverted to activities other than competitive verbal-arrow-slinging. It's time to get physical, and not just in the sack. Get out there. Go horseback riding. Take a spin on a bicycle built for two. Sign up for a martial arts class together and find a useful outlet for all the oomph you two create when you're together. It's a valuable natural resource -- appreciate it and use it wisely! Everyone will benefit if you do.
