Well, I used to be one of those women in the pit and it took it's toll - it's tough going from flirting to hating each others guts every 10 seconds! A good experience though...
Getting back to the post about a male and female trader dating each other, I can see how it can be a bad thing. We traders are competitive by nature so I can see how it would put pressure on the relationship. Not to stereotype, but a lot of guys I know say they don't want to go out with a woman they think might be smarter than them - where does that leave the smart girls?
