Hi there, aquavelvet. I'm going to be the minority and say something unexpected.
This is a difficult composite.
Your emotions naturally go into your relationship (7H MOON) which can smooth over many rumples.
I'm not wild about the fact it doesn't aspect your stellium except for a loose trine to MER and NEP. Not knocking that! But trines are typically the 'absence of' a conflict rather than any noticeable effect.
So, while your MOON is well-placed for a marriage, it's a bit like a lonely, beautiful, deserted island.
Full of potential at 0° of its sign, and clearly youthful, and a bit more impetuous (than if it were beyond 15°) but lacking the impetus to be spurred into action. This is furthered by it being in Shadow; it's harder to express, as there are obstacles blocking it from doing so.
Reminds me of a transistor in the OFF or 'zero' position. It's more than capable of conduction - but the switch has to be flipped. 'Living for transits' as they say, is dicey. (You may be concerned because other natals can 'flip that switch', too, shall we say.)
6H JUP conjunct NN has got to be the biggest sign I've seen yet for 'personal growth and expansion achieved through daily interaction'. That's great for a marriage - so long as you watch that 3H NEP-MER. Clear indicator of communication issues, too.
NEP-MER can be a beautiful thing in a composite, but squares can pose conflict. There's a natural intuition about your coupling. You can tune into each other without effort. Alas, well-meaning intentions to help the other grow and expand can be misinterpreted, or confused.
You'll both need to watch the tendency to nag. That sextile to PLU can simply help get to the heart of an issue - or get overblown into the misconception that one's seeking to control the other.
As they say, good communication is the key to pretty much negating most relational conflicts. And, boy, is it true of marriage. Essential!
Now, while you two are just bringing in a generational thing in terms of CHIRON opposite URANUS, it's tightly conjunct SATURN, which rules your CAP stellium. This is exacerbated by the quincunx to 4H VEN-MARS.
This is an interesting configuration.
The 1H and 7H are intrinsically linked by that close conjunction. In the 4H, and with the planets being the natural representatives of feminine and masculine sexuality, this is a lovely placement for marrieds.
The CHIRON quincunx is likely a karmic issue which you're here to resolve; in 9H, that seems even more probable.
There's adjustment needed in regards to spiritual development and how you 'expand your horizons' when in relationship to your sex-life. The good news is, you're pretty much on the same side of whatever issue you're tackling, but outside influences can create the necessity to adjust, reexamine, and reconsider.
This could again be linked to communication, or, as Lee suggested, unexpressed fantasies and desires, since CHIRON is disposited by MERC which is the 3R.
Conjunct the SUN at 3°, you're not going to want to let that drive a wedge. It's linked to the heart of the relationship.
Also, you have 19° LIB in your composite. ASC, in fact.
Practise anger management, and civil conflict resolution at all times. Don't let tensions rise to the physical level. If possible, attend a few workshoppes on the best ways to communicate with each other and prevent a fight from escalating. It will be well worth it.
You're a very tight unit, which can be both of benefit and a hassle. Welcome to life with a large stellium involving most of the chart. Heh!
The thing that gets me is how the MOON is so detached. One, or both, of you might be holding back, for whatever reason. Tricky, since it'd be insidious, as you're both pouring your emotional energy into your relationship. Issue is, it's not DOING anything.
You guys are propelled forth by the VENUS-MARS conjunction: affection and drive - but not emotional intimacy. Sex, even love, but not vulnerability.
This is going to become an issue on a long enough timeline. As to where the 'hold up' is, I'll have to check synastry.
I find the balance of power curious as well.
PLUTO is 1H, in Shadow. So neither of you are claiming your full power in this relationship; there are blockages.
Traditionally, we can see the position of the SUN to understand the husband or male partner; it's curious if it's in strong aspect to the female partner's chart, however.
To go with a traditional bent here, we'll say he (the SUN) has the strongest link to the power in the relationship, but there's no abuse of it; an easy, but tight, sextile. So his masculinity doesn't feel threatened, nor does he feel 'castrated' or ineffectual. That's good.
The MOON (traditionally the woman) has the more complicated relationship with power, or its exchange. The next aspect (applying) for the MOON to PLUTO is a quindecile, 1H and 7H.
The emotional partner, therefore, is feeling inexplicably thwarted; like their efforts are dissipating into the air. They have no idea why, either; it HAS to be going somewhere, right? But as the results don't yield what's desired, overall, a sense of insecurity can develop, with a questioning of the basis of power.
This is more of a potential than anything actualising or manifesting. I'd watch progressed aspects, however. These 'spectral potential' almost aspects, when between such intense points, can really drive one crazy, as you work to pinpoint the unrest or the problem.
I'm going to check your synastry now to better understand what's going on with this cMOON, as well as natal MOON / PLUTO aspects.
Back in a bit.
