Welcome to the board crazycatz. First of all, I'd like to say that you're a step ahead of the game because you realize already that this could be a problem for you. If I were you, I absolutely would not go ahead with a situation that you know with relative certainty would make you crazy with depression and jealousy. As others have said, the best way to alleviate these fears is to share them with your husband. Then he'll tell you you're crazy for thinking that way, that he loves you like no other, and that no other woman, no matter how "perfect" she may be physically, will ever be able to steal his heart the way you have.
But as was mentioned too, he WILL get really excited by this other woman...because she's new and different and, yes, because her body is different from yours. I used to freak out about this, too. Then I realized an overlooked truth: having a hard-body is only
one asset when it comes to sex. Some women may not have washboard abs, but they know how to give a man (or woman) a religious experience with their mouths. Or maybe, for the likes of Mr. intuition, a narrow supermodel type ass just isn't an asset, but more of a liability. There are plenty of men out there who really do prefer lush, feminine curves to hard-bodies. What about your confidence? Your knowledge of yourself, and what you need/want sexually? There's something to be said for a woman with the sexual maturity to get what she wants in bed.
All I'm saying is that another woman's body, no matter how Victoria's-Secret-cover-model-perfect, is nothing more than a novelty to your husband. It's not the pot of gold at the end of the rainbow. It's not Nirvana. It's not the ultimate experience for him. YOU are his ultimate experience, and when your company leaves after playtime, and you two are alone, you will see just how much this is true. Because he's going to want to eat you alive after that appetizer. He'll be wired and loaded with sexual energy, and he'll be dying to share the energy of his experience with you. This high usually lasts for days, sometimes weeks. This is him saying, "Thank-you-thank-you-thank-you for loving me this much." It's like he's won the lottery and he's looking for someone to share it with. And he chooses you. You're the first person he thinks of. You are 'home'.
I figure it would be a real shame if I had the opportunity to let Mr. intuition run his tongue over a set of rock-hard abs, because I just can't offer him that. Sorry hon, but that's just not my body type right now.
But that's okay. That's why we enjoyed swinging. It was great to be able to give him the opportunity to experience different body types, and not just restrict him to mine. I knew it didn't define me and it didn't define the quality of our love or relationship that he enjoyed other women. What we had went beyond the trivialities of sex.
