Yeah, I am not sure what to say to be honest. I think you look great, but I don't get hung up on stretch marks, chiseled abs or whatever. Hell, I have stretch marks and I don't have 3 little ones to show for it. I look at those women like I look at fashion (yeah, my wife watches fashion shows and though it hurts my hetero soul to say it I am beginning to pick up on what is 'fashionable'): I can see this amazing creation walking down the runway and think, "Yeah, that looks cool. I'd stop and take a second look if I saw it on the street, but damned if I would wear it. Give me a pair of shorts/jeans and a tshirt" These 'perfect' women are the same way - oh cool, that is nice to look at, but kind of uncomfortable and I'd much rather be with..."
Imperfections are what makes beauty in my mind. None of us are perfect, but that is what makes us beautiful and interesting. A friend (for lack of a better term) sends me links to pron. Occasionally I will click on them if bored and I always think, "WTF all these chicks look the same..." It is boring as hell. Models etc are the same. One perfect stomach looks just like the next perfect airbrushed/natural stomach. Yawn. Give me a little scar, a blemish, perhaps a stretch mark or three.
As for your husband, yeah, he is probably clueless. He's a dude. We tend to be pretty oblivious. Just let him know that he can keep his pictures to himself.
Now go check yourself out in the mirror, you look great.
