I have always had a low libido, but after dd, it's gone from low to none!! I had a c/s, so it's not that I have an "excuse". DH is contemplating buying me some pills to help get my libido up and running, but frankly - I am not interested at all.
Don't get me wrong, I love my DH and having sex with him is wonderfull. I have nothing against sex or had bad experience or anything like that. I just don't wanna - I prefer to sleep!
So I do think it's normal to be a bit "slow" after the birth of a child. You are tired and have lots on your mind, your body has changed and your attitude towards life has changed (personally)

Thumbs up for your partner not putting pressure on you!
