Well.....

Ladies...men are going to look at other women.  Get over it.  He loves you but if you bitch at him for the way GOD made him....he'll tire of you pretty quickly.  Let him look.  Hell point out some hotties for him now and then.  Be open and honest with your man...it will go a long way.  My aunt taught me that "It's not where he gets his appetite as long as he comes home for dinner."   You look too...you know you do.  You see a well muscled man jogging or whatever and you're mouth begins to water.  Wish your man looked like that don't you?  So you're a hypocrite.  You want a more stable, happy home...be realistic.  You might be the tightest, hottest chick on the block...he's still going to look.  And if you have put on a few pounds, stopped wearing makeup and so on....don't get jealous, get yourself back.  You'll feel so much better.  Do it for yourself.  Yeah....you can do it with kids.  In fact, you Should do it especially if you have kids...show them a strong woman.  If you exude confidence....your family will be happier, your kids more successful....your man...more physical and willing to please.  Yeah..it's a game...so play it better than the other women. 
Just a word of advice...you're best friend is your man in a good relationship, because if he's a good man your best "girlfriend" wants him and will most likely try to get him.  If you're a big gal...you can still be sexy...confidence girls...confidence.  Don't let anyone tell you that you aren't what he needs.  He married you didn't he?  He tries.  He loves you....give him a little something besides a daily routine.
