I agree that if he is telling you that you are sexy then he thinks you are sexy, you have afterall created 1 beautiful DD together & you have created another child together, of course he finds your pregnant body sexy - it is proof of his masculinity

Before I was pregnant my DP never really liked the look of pregnant body but he still thought I was sexy & beautiful when I was pregnant with DS because I am his partner having his child.

I know it is hard to believe when things don't look like they use to & you have all those hormones running through your body but your partner doesn't look at it that way. First of all he doesn't have those hormones going through his body he just sees you with his child growing inside of you, you may feel all pale & washed out but he sees your 'glow'.
Believe him when he tells you that you are sexy cause you are !!
