Taurus / Gemini

I'm not understanding this.
Perhaps someone can help me please?
My man was born May 21. says he is a Taurus.
WEll why is it when I find astrology on the net thats sometimes Taurus, and sometimes Gemini. Which one is he?

I don't blame him for wanting to claim Taurus. If you could choose would you want two personalities??

KocoaHauntis: I'd pick Taurus, cause thats what this beautiful man calls himself. but then I am also an Aquarius.. think that Gemini is more of a match for me, not sure.

Atlantic Myst: Thank you for that answer. Then how do I know his true traits of the sign? How do I know what he is like when he is both?
I'll read this webpage you gave me and see if I can find answers there, but somehow I think I won't.

In reading that webpage.. there is questions. What is this Taurus/Gemini like in a relationship.. and what sign is a match for him?
I have strong feelings for this man..the aura around him, and his soft sweet understanding personality is great.
