Oh inoue, I wish I knew what to say to help. I know a lot of men once they see a women give birth can stop seeing them in a sexual way as they just see them as a mummy and find that difficult. I really think you need to talk to him, be honest. Is there anything you can do to, erm, get him going? Anything you know he liked in the past? Don't feel like you are damaged goods, you have given him the most precious gift of a very beautiful daughter! You say he likes porn, would he watch it with you? I don't know what else to say, my oh has a very very high sex drive, that's why I ended up dtd so soon after birth!
Well done on your weight loss! X
