moon sign is determined by exactly where and what time you were born, since it's measuring what sign the actual moon was in when you were born. i think the moon changes signs every two days or so. this is EXTREMELY SIMPLIFIED but if your sun sign is your outward personality, then your moon sign is your inner emotions.

so for you, your gemini moon means that you're a lot more talky than scorpios normally are. also..... charming and superficial.

AND NO I LOVE WATER SIGNS i actually love writing Cancers/Scorpios/Pisces...es but it just kind of worked out that i don't have any now :( Ravi was my Pisces and he's dead
