All three parts of your Trinity are fixed signs, so you are very persistent and stubborn. You need to accept that others may not share your views. Taurus Sun means you are kind and gentle, and will go out of your way to help others. You love the outdoors, and don't speak unless you have something important to say. The Aquarius Moon means you run hot and cold in romance. You do care a lot about people, but in a detached sort of way. You need freedom in a relationship. Leo rising is the way others see you. So that's generous and warm, and a good host who likes to go out and have fun.
As far as compatibility, you need to be with someone who can stand up to your rigid idea that it's your way or the highway. This is a hard one, as Taurus is Earth, Aquarius is Air, and Leo is Fire. Unless you have other planets in Earth signs, I would say another air sign, like Gemini or Libra, or Fire signs, like Aries or Sagittarius.
