Is it appropriate for Venus Pisces male and Venus Sagittarius female to be together?

First of all, Sagittarius is a fire sign and Pisces is a water sign. The so-called fire and water are incompatible, so Sagittarius and Pisces are not suitable together. Moreover, the speed matching index of both sides is 2 (the highest point is 5, and the lowest point is 2), so it is not suitable. Of course, love is not determined by constellations. As long as it is true love, why care about what constellation? Go ahead! !
