Tired, boring, routine manners decrease Desire, Romance, Erection, Penetration, Stamina, Ejaculation, and total pleasure in married life. Why was it better before marriage and why not after? Because you changed from interesting to boring in everything for that matter. 

No surprises, no romance, no dinner or movie dating, no outings other than the must ones, so formal, so serious. The spark plugs need cleaning which need not be cleaned by us all the time, you too need to listen to inner urges. Eroticism in baths, massages, eating food, sharing seats, holding hands, hugs, shrugs, bugs all matter. Mischief, masti, massage all create magic in relationship. So remember small whispers talk big in love or sex or life too. Scents, aromas matter the most, and how welcoming is the host, surprise is the ghost, and even an ice cream or dessert can be a toast.
