Hope you girls don't mind me jumping in?
I can understand this a little bit - while I have no problem walking around naked in the house, I don't feel very good about my body
in an intimate, or sexual way. I don't think it's strange, per se, that a woman hasn't let her husband ever see her naked really, and I'm not so sure it has to do with self-esteem, it could be several other issues.
I have to agree with the others though, that said, being naked in front of your partner "should" be a normal thing. He loves you for a reason and he probably thinks you are the most gorgeous thing on the planet (I know my DP thinks this of me!), no matter WHAT you feel about yourself. Getting over this feeling about ourselves is hard though and it could be that counseling or reading a self-help book even could help.
