I think hubbies should accept all our flaws especially if it is caused by giving birth.. I'm 8months+ pregnant now yet even with all the fats I've accumulated n the ugly stretch marks on my big tummy.. N no make up anymore.. Hubby still loves to hug n kiss me.. before n after his work.. As for intimacy..it's still there.. Even if no intercourse can still help satisfy him..
If you have to slim down to attract him then it's Gona be hard to keep up especially as the years go by.. you can't escape aging n there will always be girls prettier n younger then you.. It's all about mutual understanding n trust.. I think best is to take initiative to go look for him after baby sleeps and if it doesnt work.. would definately have a talk with him to find out y he isn't interested anymore..
