My girl called me mysterious, is this a good or bad thing?

Ok me and my girl have been talking since October. We started getting serious around December. But anyway yesterday she started asking me a whole lot of random questions. Like: Am I a ual person? Why am I shy? I told her Im self concious of what people think about me and she said she's the exact same way, but she's not as shy as me.(We are both aries's by the way and she said thats typical. I don't follow astrology like that so Im like whatever...ok.) I told her I don't like being shy but she said it's alright and kinda cute because she makes me smile uncontrollably. So the day goes on and she's still asking me random questions, like she's giving me a compatability test or something. She gets all excited and tells me "Sweetheart we were born 2 days apart and our personality is almost the same." She goes on by asking me more questions like how many girls have I dated and slept with, etc. She was happy because my bodycount was low but said I probably don't have much ual experience. Which I don't; I don't sleep with random females every chance I get. So out of curiousity I ask her has she done this to her past boyfriends and she said no. I ask why and she says because IM MYSTERIOUS. Im sitting there lost because I have nothing to hide from her and don't know why she called me that and continues to ask me questions. Does anybody know if being called mysterious is good or bad?
