Simple answer to the OPs question - No, not ever. The better she looks and more attention she gets, the happier I am. She loves the attention (but not in some narcissistic way) and it makes her feel good. I completely trust her and have no insecurities that the attention is going to draw her away from me. In fact, I purchased most of her revealing outfits for her.
I've been in the lifestyle a long time and you learn fast that even when the guy of a couple is great looking and personable, his hot female half will get most of the attention from women and men. I look at the positive side of this - she is totally hot and attracts people when she's just standing there - makes it easy to make friends and the other people know we come as a pair (not that I'm so bad to look at! heheh).
What I also learned fast is that the instant you sense that one person in a couple shows jealousy, time to exit. We don't need that kind of drama.
