Sex is part and parcel of the marriage contract. Both sides owe it to their partner to meet each other's needs, in all things, including sex!
And contrary to popular misconception, wedding cake need not be an anti-aphrodisiac!
I don't plan on golfing every weekend, because my wife is going to need me to do something for her. (I literally have no hobbies, in order to provide time to her and our children.) I likewise expect and appreciate it when she realizes that she needs to make some time for me, for physical and emotional loving.
Is it always like that? No, sometimes I'm a reluctant house-husband for her, and sometimes she's not exactly brimming with desire. Bbut more often than not we are happy (and happier) to meet each others needs.
And lastly, frankly the worst sex any man every had was still pretty wonderful!
