The only one who can really answer that is your SO, truthfully.
For me, I don't care. If one of my partners is flirting, I'm hoping that she gets some response. I think she's amazing, having others recognize it is kinda cool for me.
Myself, I don't flirt. I've always found it annoying. I just live and do whatever. My relationships always spring from close friendships and always when I'm not looking for one, so it's just not my "weapon of choice".
