Having read your other post about feeling exhausted and tired all the time with the other symptoms you have, I am not surprised that you do not get "horny".
It is best to be honest with your husband and tell him that you feel really ill at the moment and it would be better to have a break for having sex every day. If you do not feel like having sex, but he is in the mood, you can always do a hand job on him.
Everybody has different libidos, and although some people may have sex every night and that be normal for them, others can go for weeks or months before having any sex.
As we get older the libido changes. In your case you have a young child and you are too exhausted to feel like having sex and feeling horny every night. You need a good rest and get well.
Best wishes.
Hi Tx, Well I do know what your going through, and I'm the husband, went through this same thing years ago.
But with bringing up your young son, house work, and, and, and the rest that goes with it, means that your not in the mood, its best that your husband just waits for the weekends, the break will do you both good, if you can try and promise here some extra time at weekends, if he can take baby away from you for a couple of hours, that way you get a break, take in some air, take a slow bath or a long shower, if he can get him to cook the Saturday night meal, all these things will help you unwind for a better sex life with him, and should with you.
A good marriage needs a lot of give and take, if its ever going to work right, I think yours needs to start now, before it gets ugly all over sex.
Do hope this helps.
Good Luck
