There is an element of fear in me, I suppose, but that's more a fear of what wiould happen to me if I fell for her. I've seen what it does to many a man, and I don't like what I see (eg. ignoring friends, losing faculty of reason and perspective etc.)
As for courting itself, it's more that I simply have a low tolerance for women. That is, I can enjoy their company when it is distilled by other male companions, but I wouldn't want to be left alone with one for any extended amount of time, especially if there were a social obligation to make conversation, as would be the case on a 'date'.
