Agree with PinnerPaul, generally much better behaved, but, just like in men's football, there are rivalries and they can ramp up the tempo / aggression levels. Get certain Herts vs Beds teams, or Middx vs Beds teams, and you are generally going to be in for a lively game. I did the former a few years ago, away player off for a shocker of a two footed tackle (she nearly took me out with it as well), she then had a pop at the home manager on the way off (tunnel is between benches) which caused a major skirmish. Then there was allegedly a fight in the bar after, I was about to go in, heard glass breaking so decided better of it, forgoing my sandwiches and pint, and went home. That way when the FA called me a few days later to ask what had happened I could truthfully say that I didn't have a clue over and above what I had reported for the game itself.
In another game the home team manager lasted 45 seconds before I dispatched him to the stands, all over a dropped ball on the half way line of all things, and the benches had been at each other's throats even up until that point. I'd already decided that I was operating with a vastly reduced tolerance level that day and the first outburst from the benches was going to result in an example being set, he walked straight into the trap (was before cards could be used for non-players).
Not WNL, but one women's game a couple of divisions below developed into a full blown riot with police called and CS spray deployed. So never assume that women's games will be trouble free, they usually are but not always.
