This never used to be a problem, but since a long period of illness and stress my libido has never really recovered. I used to have a really healthy - ahem - 'appetite'.
DS is a teenager and I have not just had a baby, so it isn't even anything like that and I think 35 is too young to be hitting the menopause.
I just feel tired and can't muster the enthusiasm. Plus, me and DP have different body clocks. I work from home and sometimes start work at 4:00 am. I am a natural early riser and get more work done and can concentrate better if I get up early. DP works 9 to 5, so I'm knackered when he might be feeling frisky anyway.
I'm a bit worried about the impact this could be having, but I'm not prepared to sacrifice my productivity work-wise as we need the money and my early morning work time is also my 'me' time!
I still find DP attractive, but I do have body hang-ups which don't help. Also, our families live far away and DS is still only 13. He is going through an antisocial teenage phase where he never wants to stay over at his mate's house etc. So, couple time is like gold dust non existent. 
Is it worth going to see my GP about my low libido? Can anyone help?
