Pisces with Pisces : Yes sexual compatibility will be great as they both click , but is sex is enough to sustain a relationship ? No we need more than that. As we know Pisces is dreamy, emotional , sensitive and lazy with weak will power as compared to other signs. Here we have two individuals both having similar traits. Pisces need some one to take charge of their relationship, some one strong willed who can provide the security. Both are emotional and will make huge demands on each other on a emotional plane , which will drain them totally. Both will be overly sensitive and some times very negative and pessimistic which will make them sad and become rudderless in their relationship. When it comes to being practical both will fail miserably, as both are weak and there won't be any one to take charge and guide the other towards the right direction. Sex won't take them far and sooner or later things will die between them.
