the increased wettness could be related to changing hormone levels. I know it seems like I'm wet pretty much all the time and I've never really given much thought to it. In other words it seems to be normal for me. It think in your case changing hormone levels could also explain the increase in horniness!
My guess is thats its the extra fantasizing. Goes to show you fantasy is good for the libido. I'd say keep it up! You can always masturbate if he can't keep up with you.
I would agree that hormonal fluctuations during the month are usually responsible for increased discharge and lubrication. I think men are mistaken when they assume that a woman is wet only when she is aroused though. Just not true. I go through a period every month, just about mid-cycle, when I'm wetter than any other time but it's not because I'm fantasizing more or more interested in sex.
