I would think it JUST normal that anyone look at s really sexy person should it be a lady or gent or couple.
In fact I think it abnormal if they do not look!!!!
But about jealousy in a relationship...YEAH the little slimy green man pops up in many relationships ,and most men are NOT allowed to be normal....or ladies for that matter, but here in Swing-world, I think it is NOT a problem.
People like it if the other notice that you have eye-candy on your arm or you are the eye-candy on an arm, and lust after someone,or they lust after you.
Me personally...I love Looking at people,please notice, I say people, not a gender.
I tend to show or say when I find someone sexy or something sexy about someone.
I know my girlfriend likes big bottomed girls, so I will direct her gaze to many a proud wriggling *booty*....
When we first stated out in our relationship,I know My girlfriend got *off* on me showing a little jealousy, so I used to show her some nice woman....but also add *I will allow her to watch, but she is not allowed to touch*....but Inside I would smile a BIG Colgate smile of a Cheshire Cat....knowing she is enjoying these days she has learned that I am not the jealous will smile with me ,when I say I will slap her bottom if she touches.
I tend to over look the really *beautiful people*/the Ken and Barbies of the world, and look and see the shy ones,the flawed ones,(I am after all also one) I see how they shine in their own each and every person has something really beautiful about them.
But why have eyes and appreciation of something, and you are not allowed to use it??
When I was still involved, the idea of someone else looking at your partner made me feel very proud. To think that they would like to stand a chance of getting it on with her where I can say, at least she's going home with me tonight. I always loved it. We discussed on numerous times when I saw an attractive lady with a nice figure and she would also comment. Same thing went when she saw a stud. That's just how we were.
