Hello,
I tried to interpret my 7th house and I'm confused, because my DSC and my DSC ruler Saturn aspect everything in my chart.
I got:
1. DSC opposite Sun/Venus/Mars, trine Jupiter, square Chiron
2. DSC ruler Saturn in 11th trine Moon, sextile Mercury, quincux Neptune, quincunx Uranus/Pluto
It cannot mean, that I find just anyone attractive and any kind of relationship suitable, that wouldn't fit to me at all. I'm very cautious with other people, quite slow to make friends and I've always been even more cautious with romantic relationships. I'm almost 45 years old, so I don't think, that could change one day.
My 7th is in Capricorn and I usually get with Capricorns well along, but my 5th is in Libra and my 11th in Aries and I've never felt attracted to any Libra and I've also never befriended any Aries.
What does my chart say about relationships?
The sign of 7th house itself is the primary indicator of relationships, and thus your cautious approach makes sense.

As it says here, having Capricorn on the 7th house cusp would indicate "shyness and reserve." Basically, you would conduct your relationships with a Capricorn-like tendency, which is almost exactly what you've described.
Now, as for Saturn in Aries, that probably wouldn't indicate what you're thinking. The fact that Saturn is your 7th house ruler, doesn't change the fact that Saturn is actually a planet that indicates structure, difficulties to overcome, and limitations.
Saturn is in it's fall in Aries, which means that you have difficulty structuring your life. Look here, for instance.

You'll have to do hard work and probably become somewhat self-reliant through it. You'll constantly feel that you're thwarting yourself, or "driving with the breaks on," as they say. You may also be somewhat aloof and have difficulty attaining harmony in interpersonal relationships.
Aries and the 11th house in general looks to be a difficult spot for you. You have Chiron and your North Node there as well. It means that you're actually expected to learn how to assert your own individuality and identity, but Chiron and Saturn being there indicate that you'll have difficult obstacles to overcome in the process of doing this. Saturn shows that the goals themselves, and learning discipline might be an issue. Chiron shows that you bear a wound to your sense of self, and need to learn about valuing yourself all over again.
Now, that said... an interesting aspect you may have overlooked in looking at rulership, is the importance of house placement of house rulers.

Ruler of the 7th being in the 11th means that your relationships may ultimately feel more like friendships, and that you need someone who shares your long-term dreams, interests, and goals for a partner. It suggests passion would be less important than supportiveness and compatibility.
And all of the above stuff about Saturn, Aries, Chiron, and the North node... is all playing out in the 11th house, which involves several things. Future aspirations, your peer group and casual friendships.
Saturn being in the 11th house alone would indicate that you have trouble being comfortable around acquaintances, but there are so many indicators in that direction that I scarcely needed to reference it. You would have difficulty belonging and feeling accepted in a group, which supports all the ideas above.
And I also have an idea about how your Leo moon manifests. It may seem odd, but bear with me.
Your first house is EXTREMELY active. Your Sun, Mars, and Venus are all in there. People meeting you for the first time would see right down to your core, as your ascendant is in the same sign as the Sun. They would also immediately get a sense of what upsets you, and what you find aesthetically pleasing (perhaps through your clothing or hairstyle). Even if you're a quiet person, you likely have an overwhelming personality that doesn't really hide much behind the surface. You are probably don't have much of a mask, and likely have difficulty hiding your emotions even if they're embarrassing. You're very "real" in some way, and that probably scares some people.
All the Leo moon is really saying, in your case, is that your emotional nature is right up front, and gives off a sort of intensity. Unconsciously, your emotional nature and feelings is not at all ashamed of who you are, even if consciously you may try to be very modest or self-deprecating. The rest of your chart says it as well, if perhaps in a clearer way.
Basically, all that messy emotional, personal stuff you might think you're hiding... you're probably not hiding it as well as you think. It bubbles up in spite of you, in subtle ways that no one would likely ever point out to you. A lot of times, people can read more into body language and phrasing than you would expect. They can especially read anxiety or embarrassment, and often back off in order to alleviate it. This may be the opposite of what you want, if you're pushing yourself to overcome it just to be in the situation at all.
