Your intuitive, psychic awareness of each other will deepen over time. There will be plenty of times when you can tune in to each other's feelings without any need for words; you'll know just what your partner is thinking and feeling, simply by being ultra-aware of them at a spiritual or psychic level. Being intimate with each other in this way will change you both over time.
You'll learn to develop your more sensitive, feeling side, and you'll both hone your intuitive skills through the course of this relationship. You'll use those intuitions to dig deeply into each other's minds and psyches, and uncover hidden memories, feelings and desires that lie there. This will change you, especially if the rest of your relationship is supportive, loving and warm; you'll have a soft, safe haven in which to evolve at an important personal level. Since this is an overall positive and harmonious influence, this shouldn't be an unpleasant process for either of you, but do make sure not to don't cross any boundaries your partner doesn't want you to cross! You both still deserve your privacy, even in an intimate relationship like this one could become.
