@sara007 A 7 th House Gemini individual can talk a lot because people with this placement see communication as their best solution to any problem. They can get close to people through different conversations, make friends at different social events and get together with those who like to talk as much as they do. Does this describe you yourself? If it does it also describes partly your perfect mate/s.
Sun in Sagittarius?
This is a sign that loves nothing more than to live life large. When things are going well, those with Sun in Sagittarius are typically convivial, outgoing and good-humoured. Freedom is important and they will be willing to take a risk. This sign requires the space to roam unimpeded, and will usually give others the same in return. Does this describe you as well? If so it also describes the second part of your perfect man/men as well. M
Mars in Aries is bossy and pushy, often with a big mouth. Your sex drive is very strong, and you are easily aroused. You like spontaneous acts, and are addicted to the conquest. You can be quite selfish and quick in bed, and may not be fond of foreplay due to your impatience. These people are the wham–bam thank-you-mam kind of people. Does this describe you? If it does it describes your perfect man/men as well.
Now if your were attracted to women instead of men I would use the moon and venus instead of sun and mars. But I would still use the 7th house cusp which is Gemini in your case.

I haven't really tried Vedic yet but Whole sign is way more limiting and far less accurate for me than Placidus or Prophyry. In Placidus and Prophyry I have 2 interceptions of houses and 4 interceptions of planets. But to fix those I just use the planet rulerships instead of the intercepted sign which serves me far more. I use the ruler ship of the houses itself for those 2 houses too which serves me quite well. Also My 2 other signs that are doubled up in Placidus serve me quite well too.
In Whole sign I don't get the doubled scorpio and taurus which is very helpful for me.
Capricorn only serves me with Saturn's rulerships and is worthless in my 2nd house and does not describe who I am with the moon or Jupiter. Cancer most definitely does not describe my Venus which whole sign would say I am but is obviously wrong.

@sara007 I just realized I already posted the perfect man/mate attributes for another question you had about long term relationship. But it told me it's waiting approval on this site.
Jupiter in the 7th house means the person wants intensity in one to one relations. It often indicates a philosophical and wise partner. They are attracted to open-minded and tolerant people in all forms of partnership not just marriage or lovers.
The 7th house cusp is just as important as the main sign that is in it.
A Scorpio moon in the natal chart suggests a person who is deep and passionate, and who will get what they want. They are very capable. The Moon in Scorpio indicates a mysterious, reserved person. You are not someone to be taken lightly. In your relationships, you need intensity and passion, and you can be pretty possessive.
A lot of people have interceptions. An interception is where in more modern house systems that are not whole sign. Two opposing signs do not have a house cusp and those signs do not bear fruit. But 2 other signs are doubled in energy and definitely bear fruit.
Without this person's chart or knowing them personally I do not know if their Moon or Jupiter is intercepted or even doubled up in zodiac energy.
But Jupiter in 7th house definitely means the person is attracted to intense open and tolerant partnerships in all areas of life including but not limited to lovers and long term mates. Now you mention the moon too so intuitively I feel there as an aspect there. But without the house the moon is in I can't know exactly what the aspect between Jupiter there might be.
