My wife is 33 yo and said she does not feel ...

Yeah, I think you should. I was like that when I worked 10 hour shifts 5 times a week, and I'm a guy!

Seriously, tiredness really does kill sexual urge. If she works harder than you do, do your best to do as much house work as you can, so she'll be a bit less tired. It could help.

Good luck. 

Hi,

Of course you should trust her. Working 60 hours a week is tough and tiring on anyone. Working long hours and stress will often lower ones libido and interest in sex.

Good luck and best wishes. 

ask her what should you do about sex and see what she says. she should be supportive but may just be tired. ask her about seeing a marriage conselor. maybe you could try giving her a massage or a good rub down and some oral to make her feel good and then try easign into more making love. what about holding each other or kissing is she too tired for that also?
