Changes of motherhood affecting my marriage and sex life...?

[Rhonda H]

My husband, while totally loving and devoted, has completely stopped trying to have sex with me. I'm 29, 7 months pregnant with second child, and while I think I look very good for a pregnant woman, and he tells me I'm sexy all the time, when it comes right down to it, he doesn't really try to have sex with me anymore. The other night he said it was because he "didn't want to hurt the baby", which to me seemed like a nice way of saying that my pregnant body wasn't turning him on right now. When I try to make the moves first, it almost seems to turn him off more. What should I do? Like I said, he's sweet and loving otherwise, but seems uncomfortable with sex, (and has been since our first child)...I feel like because my body never went completely back to normal that's he's just not attracted to me anymore. Guys, is it true that your woman/wife, after children, her body's changes permanently turn you off from them sexually? (BTW, I know he looks at porn.)
