Which astrological sign is most prone to cheating?

Ashley Madison, a dating website explicitly for those who are already in a relationship (their tagline is "Life is Short. Have an Affair") have analyzed the astrological signs of their members to determine which star sign is most likely to cheat. Here's what they found:
- Among men, Pisces are the most likely to cheat, while, among women, Geminis are the least faithful.
- Aquarius and Cancer are the next most likely men to cheat; Aries and Virgo women come in second and third.
- However, female Geminis also get their comeuppance: They're the most likely to be cheated on. Among men, Tauruses are most likely to have spouses who cheat.
- When it comes to duration of affairs, Aries men and Virgo women are the most prone to maintaining a long-term extramarrital relationship.
What do you think? Is there any stock in star signs?
Gemini
Married to a gemini. Pretty sure he's faithful. Am an aires and am faithful.
Yes, after reading these stats, I would have to say that there is some validity to this and what astrological signs reflect based on my experiences and that of friends.
But I would think we should not base our relationship partners on following these statistics as love is love and good long term relationships can weather any storm.
Geminis rock
Aries and I'm a Gemini
Two geminis, together for 18+ years and loyal through it all. This horoscope stuff is bologna!
I am a Scorpio and was cheated on by another Scorpio; but _ ended up married to a Scorpio (not the same one tthat cheated on me!)
Pisces.
P.s. I never cheated.
In defense of us gems.. Once we are with someone who deserves us, we are very loyal! Haha!!!
Scorpio -- proposed to me and married me when he knew he wasn't divorced from previous wife. Cheated on me constantly (didn't know) until he finally kicked me to the curb. I don't think it had much to do with the astrological sign, just an immaturity.
