OK I'll share here - I used to read tarot cards and compile astrology charts when I was saving up to travel to Australia for a year. So I'm pretty knowledgable about this! (Ahem).
You should get on fairly comfortably with fellow fire signs - Sagittarius, Leo - and there should be a 'spark' with Libra - your opposite sign, ie a magnetic attraction albeit spiced with some friction - though this all adds to the excitement, no?
Incidentally, I'm Libran (!) - but the 'opposites attract' thing tendsto be more applicable to relations with the opposite sex.
