Wow! Understatement! Gemini and Sag are opposites on the 'wheel' (air and fire) Add an Earth sign (Virgo) and I bet the sparks can fly! By the way, good on you for choosing an 'opposite' to mate with...there will be a lot of personal growth in that relationship (if you do not "kill' one another first!) LOL Personally, I did not marry an opposite...but I chose a Fire/Water relationship...also very challenging.

Oh, and by the by, OP - you chose a great sign...the best (or sometimes 'worst') of BOTH!!! ;)
