That pretty much sums me up too all the time, especially at work. At work one of the girls who I'm generally messing around with says I flirt with anything even the boys, my best counter to that has been "hell I'll even flirt with rocks if the mood takes me, being an animate object isn't neccessary you know." I tend to flirt a lot with female customers, it's quite funny because I tend to end up selling quite a bit of stuff too. I usually end up with women who don't know or understand anything about consoles and frankly am bored by the idea of them but they wanna get their boyfriends/husbands something they'll enjoy for xmas and so buy them consoles. I'll sell the console and to keep the woman interested, sharp and on her toes and so she has fun doing her shopping I flirt a little with them whilst doing it. Even a "hmm I wouldn't mind seeing a video of you doing the hula hoop on wii fit" can go in there, so long as they're laughing and they're not having a bad time it's all good.
Outside of work I tend to tone down my flirting big time, mainly because I have a girlfriend and flirting in front of her with anyone causes arguments I don't need. However I do still flirt outside of work even if she is with me so long as we're clear that it's ok to do so in certain situations. My flirty nature makes it hard for me at times to be in relationships because I have a lot of female friends and when I'm chatting to them there will undoubtedbly be flirty banter between us and no matter who it is, girlfriends are NEVER happy at that point.
