It's easy to have affairs these days, and in the current economic times, it's not miserly to turn up at pizza express with a 2-for-1 voucher and still impress your date. Just don't buy cheap wine or you are a gipper.
I was trying to decide who I'd most like to have an affair with and I narrowed it down to Kate Beckinsale and / or Naomi Watts. They're both beautiful, and are probably good fun to have a drink with. I also think I could get away with telling the girlfriend I was having an affair with either of them and she'd have a certain grudging respect. But I wouldn't let her join in, there probably wouldn't be enough jelly and ice cream to cover us all.
So, what's yours? If it's a same sexer, that's fine, I won't judge.
