The effects of this aspect are probably subtle, but that doesn't mean they can't be important. You have a tender and compassionate heart, and you've always wanted to make a difference in the world -- to make it a better place for someone in need, perhaps, or even just to contribute to the greater good by being the kindest, most compassionate person you can. You treat everyone around you with respect, and the way that you naturally are is an inspiration to your lover, who has deep wells of power and emotion that could be paired up with your sense of compassion for great results.
The two of you together equal personal power plus strength of ideals. If there's a cause that's meaningful to both of you, by all means, pursue it -- you could get further as a team than either of you would have on your own. What form this takes is up to you; as already stated, you can keep it on a personal level, and just inspire each other to meet the world with compassion and grace, or you can take it outside and get involved with something humanitarian or spiritual, some movement that makes life better for a lot of people. Working together at a camp for disadvantaged kids, volunteering at a soup kitchen over the holidays -- any activity like this would be a wonderful expression of your combined talents and efforts.
