There is validity to what you say as well. There are people that are just like that. It's like they are people magnets and other's are just drawn to them. There are also people that unintentionally can give out certain vibes. For me for example, growing up and in my young adult years, I used to be considered a "natural flirt", not because I was actually flirting, but because I had a way about making other's feel comfortable around me. This could sometimes be misconstrued. As a result I learned to be a bit more reserved especially when dealing with a member of the opposite sex as to ensure that I did not give out the wrong impression.

I think it is another key element the openess you have with your wife in the sense that you do not hide such things from her. I mean it's not like you gotta go home and say "hey honey today at the supermarket check out the cashier smiled at me" but say in an instance where an outright action was taken such as similar to the ones that you described, you're telling her about it show's you have nothing to hide, which often means you did nothing wrong. However, if you didn't tell her about it and it somehow came to her attention, even if you said your part of what took place, she'd wonder why you didn't tell her about it.
