After other people's view points please
Been with DW for 6 years, married for nearly 4. We have 13mo DS
After finding out DW was pregnant we didn't have sex, she had some minor complications that gave her some pain and discomfort. I distanced myself from the subject and just got on with things, I have never been the type to beg or ask.
Since DS was born we have had sex 4 times. So in two years that's it. In the last couple of months I have been finding it increasingly difficult. I attempted to talk this through with DW this morning, in her words:
I just don't think about it
I'm not that bothered about it
I enjoy it when we do have sex
I just don't have the same drive as you, I can happily go a couple weeks without (at this I pointed out it has been 2 months which I think is a bit different!)
This is all compounded by some restrictions on DW part. Has to be in our bed, under covers, in the dark, always same position. She doesn't like giving or receiving oral, or me touching her with my hands 'down there'
We both work, most of weekend is busy so this possibly leaves one chance while DS is napping. Weeknights are no good as his room is right next to ours... So basically we never get a chance...
I struggle to get my head around enjoying sex but rarely wanting it. I get she may be a bit more body conscious, I regularly compliment her, tell her how beautiful she is. Usually the reply is an eye roll...each time I try to discuss this it devolves into an argument, I get this is hard after having kids I don't expect to have sex several times a week but the gaps between are 2/3/4 months it leaves me feeling so down and upset. It's the 'I don't care, so it doesn't matter what you want' bit that really hurts 
I am considering counselling, any advice?
