HI
I read your reply an yes you are not silly and you do have a problem you love your partner with all your heart an would love to show her your love an affection you have for her in the bedroom.
Routine,shift work has alot to do with it is possible,low sex drive to high sex drive that wont work either cause someone will always be disappointed.[an we know who that is,damn]
It seems to me your parnter has lost her PASSION,FIRE, ZING,SPARK we need to find that again,im shore the passion was there in the beginning,what was it about you that turned her on to the point were she couldnt keep her hands of you.
We are going to RIP this problem apart turn it upside down an inside out until we find an answer or end up BALD from ripping our hair out
All the best OXOX
