DH and I married for 5 years, we have a 2.5yo DS.
Before DS we had an ok sex life, probably got intimate 2-3 times a week, sometimes less. I have much lower sex drive than him - he would prob take it every day, whereas I am happy with once a week or less. When we first got together DH would handle the rejection of not getting it as much as he would like badly and get in moods and throw his toys out the pram. This was quickly addressed.
Fast forward to now and sex life has gone downhill we are intimate maybe once a week sometimes less, mainly due to me suffering from PND and thyroid issues (feel fat, low libido, knackered all the time) basically it isn't high on my to-do list. I only really fancy it at random times of the day, usually DS's naptime or after we put him to bed - mornings are a write off because DS is awake at the crack of dawn and by the time we get into bed at night I am ready to be asleep asap. I've explained this to DH so he knows the situ, and yet sometimes he will still try to "initiate" (i.e boob touching, bum squeezing) and I have to move his hand elsewhere or flat out say no.
Every month it all blows up into a big row. Once it gets to a week or so without intimacy you can cut the tension with a knife, he basically starts ignoring me and barely bothering to speak to me. He says he is sick of rejection and 'switches off' at this point, but to me it just seems like he is in a grump because he wants sex. I have really been trying to be more engaged with him, to cuddle and kiss more and just generally be more attentive but he says he hasn't even noticed a difference. I don't know what I can do - I can't physically force myself to want sex more.
I'm fed up of having the same argument every month, and can't see it going away. I'm seriously considering walking away.
