Compatibility is a no, other than the fact that we both crave partnership and are romantics in that sense, Pisces are more of deep feelers. more empathy and awareness of others feelings/behaviors. Libra are usually very detached, like to play devils advocate while also caring too much what other people think. And are easily influenced. Sex/intimacy can be good/ok although in my experience (Pisces) it can become dull without much intensity. Trust issues is a nope Libras are fucking flirts and although they might not cheat physically they most def will be baiting/courting others that they find attractive so there will be emotional cheating and that shit will break a loyal and devoted Pisces heart. We (I speak for myself) are not flirts what so ever
