Not sure if this is the right section but here goes (regular poster NC etc)
DD was born almost two years ago and my libido has never recovered. She is DC2, no problems after DC1. Initially I put it down to newborn stuff, recent birth then breastfeeding. Stopped BF a year ago and it hasn't returned. I'd always been fairly highly sexual, up for experimenting, massive urges etc but honestly, if I never have to have sex again ill be happy 
DH remains with a high sex drive, we DTD several times a week because I feel so guilty. I'm not attracted to anyone else so it's not that I just don't want sex with him. It's fine once we get ping but I spend most of the time willing it to be done with quickly, even if I reach climax (which now happens 1/8x when it used to be almost 100%). I just can't be bothered and even go so far as to say the idea just turns me off, so I don't think it's just tiredness either.
I'm not convinced I'm as in love with DH as I once was, we rub along fine, I do often feel stifled by him though. I don't want to LTB, but often with we could just have a platonic marriage.
It's bad, isn't it? What can I do?!
