I am in confusion... my wife have no interest in sex from last 1 year
Myself 30 years old, wife is 28 yrs. Old and we have made marriage before 6 years. Now my wife have no interest in sex from last 1 year, when I have mood for sex and discuss to her about this, she told me about tiredness and sleepness and try to avoid sex as possible and when I say to her about sex more and more times, she have ready with no mood. I think about extramarital relation due to my wife behaviour but I don't want to do this. What should I do??
