Okay, look ...
1. I do flirt a lot, because it's fun (especially when I'm p*ssed). But, if the other person is attached, I would only do it if the other half was there, so that it was fun, and not sneaky.
2. I have had a couple of "encounters" with two of my friends when we were all a bit trolleyed BUT that was after I had stopped seeing Pencil Dick (and as Thing1 and Thing2 are also both girls, I'm not sure that it counts anyway, but let's not go there tonight).
3. If I am in a relationship I am one hundred per cent loyal. Okay, you don't know me (winebuyer does, but not much), but all my friends know that for all my joking, when the chips are down, I am fiercely loyal, both to my friends and yes, even to Pencil Dick (when we were still together).
The bottom line is ... I know where to draw the line.
Flirt, have fun, enjoy life ... but don't ever cross the line.
Sharing yourself with another man is the wrong side of the line.
