What's fair is fair. Post a Daily Chore List. This is for couples want to:
a) Avoid confrontation;
b) Support the other;  
c) Promote peaceful cohabitation. 
Both people scratch off items when finished. Nobody needs to sulk, nag, or get upset. And everyone wins!
First, it's never a good practice to make a mountain out of a mole hill. Well, I gotta ask, do you have a written or verbal agreement for dividing up house chores? If not, make one.

Secondly, this is an easy fix for most couples. Don't beat the issue to death. Nobody likes to owe their partner favors all the time. It puts them in a one-down position. Write out a few ideas and discuss how the list changes with the seasons. Who shovels the snow? Who dusts? Does one cook and the other clean up? How about laundry?

Lastly, try the Extra Chore List  method that my parents used. My mother would write down a 2-3 item list for my dad and then post it on the fridge. As a stay-at-home mother of five, she did nearly all of the household duties. My dad respected the fact she couldn't do everything; he simply crossed them out one at a time. If it was urgent, she'd put a star by it.

With both parties working, either person can add a specific chore with a target date.Who is better equipped to handle it. If neither has the muscle or expertise to do it, call an expert. 
If you are asking yourself if your relationship has gotten boring, it has.  The question is, what have you done to expand your own horizon. Learned a new language?  Signed up for a dance class?  Read any stimulating books lately? 

Start with yourself first. Your partner will be motivated to catch up with his/her fascinating partner. Be the inspiration. Do something once a week other than watching TV together. Schedule a new activity bi-monthly. Discover events in your community. Go to a farmers market or an art museum. Listen to a live band. Visit a town nearby that you've never seen before. The list is endless. 

Explore. Be creative. 

On the flip side, couples need to maintain their own hobbies/activities without insisting the other come your event. Smothering behavior is not attractive. If you love live theater and your partner hates it, for instance, go with a mutual friend who enjoys it as much as you do. Obviously, you can indulge your partner once or twice a year. Your significant other might enjoy a single baseball game while you go to a dozen more every season. 

Two independent personalities blend more happily when boundaries are respected. Keep your identity in tact. After all, that's why you fell in love with in the first place!
Almost everybody does!  Mine was Terry O'Toole. I was just 17 and was known as "goodie-two-shoes." Didn't smoke or drink (much). Yes, I was a virgin; but I still wanted to know what to do to drive him crazy and how to be competent at kissing etc. We fell in love. Four years older, Terry never rushed me into anything I wasn't ready for; he never pushed me too far too fast. Such a patient loving teacher! Believe me, 18 months of experimental sex, without intercourse, is the perfect foundation for a great sex life. Can't thank him enough. 

Try to recall what is was like to have that first love. Then bring back the enthusiasm and passion to experiment into your current relationship.                                            bit.ly/KissToday       bit.ly/SpiceSexUp
