Gemini woman have a really bad rep, I think often unfairly. I think they are very picky and will not decide easily to cheat in a relationship. Often they are either too flirty or too generous. They cheat more in their minds than in reality. They always look for something exciting, and once they get bored they become unpredictable and can have difficulties maintaining relationships.
I wouldn’t think anymore then any other person might be inclined toward. Same with the question about Cancer Women.
You might be well served by checking out in the local Library, the older books by Linda Goodman who wrote “Love Signs” astrology. She’d give you the straight poop on each sign as she saw the inclinations to be. The late Goodman wrote many books, so any of them are worthwhile, imo.
