Your sexual connection's definitely given a nice boost by this aspect, but that isn't even the best focus of its influence! A positive sexual bond is just an outer reflection of a more inner characteristic of your relationship. You're a naturally positive and energetic person, and those qualities of yours serve as an example to your partner, inspiring them to push forward more boldly and brashly in their own life.
You actually help them find their path in life and stick to it better than they might have on their own, by serving as a very positive example for them. Their vulnerabilities and fears are flushed out; you teach them, simply by example, that there's nothing to fear about either success or failure. And now they're much more motivated to grab hold of opportunities that come their way. You can really help them in their business, or on a more personal level, because any problem your partner might have or any area of their life that needs improvement is naturally sparked up by your presence in their life. You help them to learn the benefits of taking the initiative in any given situation, of being a leader instead of a follower. And again, your sexual connection helps both of you to get in touch with your inner energy, to bring it out and focus it for use in your daily life.
