I am mum of 2 DDs, have v stressful (supposedly) part-time job, and look after home single handedly. Unsurprisingly come 11 at night when I crawl into bed sex is the last thing on my mind.
I think the only way DH would be happy is if he got his leg over every night. When we have sex its great and I enjoy it. But within 2 days he'll be hinting and complaining that we never do it. If I wasn't knackered once a week would be great. But this would not be enough for DH. His dissappointment in our sex life results in him suffering bouts of depression.
To be honest I'm so sick of it I'd pefer never to have sex again.
