I had to chime in on this one! I have my Sun and Moon (and some) in Virgo, and a Gemini ascendant that progressed to Cancer a while back. I bought my first deck of tarot cards while this progression was taking place. I am intuitive but not without the aid of cards, they open a door for me that is otherwise shut. On the other hand I can read body language very clear. It's hard to explain, but I can tell if there is something not right with someone. but I don't know exactly what it may be, I just know something isn't right. I I also come from the Neptune in scorpio generation, which is my entire 6th house, so reading cards and charts etc. are very much a part of my daily life. On top of that I have transiting Neptune in my 9th house. So I would have to say that being intuitive or psychic is not limited to just your sun and moon, Neptunes placing and transits are equally important, as neptune rules our psychic abilities, spirituality and dreams more so than our Sun and Moon. It is true though, the more personal planets in water signs, the more the intuition is heightened.
