Pisces is a dreamer where Gemini is more of a mind playing character. Both have a tendency to manipulate the other and this can get in the way of their relationship if they let it.
In the bedroom the Gemini is more of the adventurer. Gemini’s are not usually inhibited and can be very kinky at times. This can be a turn off for the sensitive Pisces who seeks emotional attachment and romantic soirees. As long as these two signs can keep honest and communicate their intentions with each other the relationship can grow and develop. But don’t expect too much, Gemini and Pisces are generally incompatible astrological signs.
