life

we have been married for more than 15yrs why cant she show me that she desires me when having sex.(befor,during,or after), If i didn't initiate sex we wouldn't have any.If i say anything about it she gets mad and wont talk anymore.i show her that im interested and desire her.(she likes that ). has any one in answers been threw this ,I need some good advice this has been bugging me for awhile.

when having sex ,i have to initiate it all the time .my wife only wants to do it 2 ways her on top or me on top,she doesn't want to do anything else.befor we always did it in diffrent positions i work 72 hours a week , she is a stay at home wife.

I WORK 12HRS A DAY ,STILL I MAKE AN EFFORT TO DO MANY THINGS WITH MY FAMILY (WIFE &3 KIDS ).I WORK THEN COME HOME.THIS IS MY ROUTINE. ON DAYS OFF, I TRY TO SPEND TIME WITH MY WIFE ,SHE RATHER LOOK AT T.V. NOT TALK WITH ME, THAT FUSTRATES ME. SHE SEEMS TO HAVE THE SAME ROUTINE EVERYDAY .ONLY WHEN SHE FEELS LIKE DOING SOMETHING SHE WILL DO IT.SHE HAS NO SEX DRIVE ,I INITIATE IT ALL THE TIME ....WHAT IS GOING ON ?

I don't understand.last night about 4am ,as we were sleeping .i turned to my wife's side as soon as i put my arm around her waist she immediately pushed me away and told me to stop touching her and let her go to sleep.she made me feel like a rapist .now i am confused .i need some advice......
