Thank you Re: Composite
* Composite Mars conjunct his sun, composite sun conjunct his Mars. Sexual interest there, all Mars related themes including irritation.
* ASC quincunx Mars, which is trine Pluto at the top of the chart. So, ASC-Mars-Pluto forms a Pythagorean Triangle. Again, sexual interest, but tension, like an argument could break out at any time. However, if the relationship lasts, this triangle could mellow out...it's a learning experience.
* Sun conjunct Chiron reinforces what I said above...there could be arguments and pain, converted to healing over time as you adjusted to each other.
* Wow Saturn conjunct NN exact, in Capricorn, in the 12H. That looks important. May not be the easiest connection, but highly rewarding when it does all come together.
* His Venus is on the composite SN -> interesting, since your natal Venus is near your SN. This could just feel familiar to you. Plus, your Neptune-moon-Uranus is on the composite NN. I feel that when the composite nodal axis is conjunct each person's natal planets, there's a magnetic pull. In this case, you have a Capricorn moon on Cap NN conjunct Saturn...may help develop your moon, not only with becoming even more Saturnine, but expanding its understanding of all the ways Saturn and Cancer/moon energy can play out. Breaking out of old habits.
* Composite NN + your stellium on his ASC, that looks great, especially since he is a Cancer, he might love the feel of your moon on his ASC.
* Also I love his Cancer stellium squaring your nodal axis.
* And I love the Pluto-Jupiter conjunction...auspicious for wealth (Bill Gates has that natally.)
* Chart ruler, Uranus, in the 11th house, conjunct Neptune. Normally I would think 11H Uranus as chart ruler is better suited for friendship than romance...just a guess. But Neptune adds romanticism, forgiveness, calm. The Sag moon in the 11H also...looks exciting.
* Composite sun exactly conjunct Mercury, with a Gemini IC, could mean that you are like-minded, have some telepathy between each other, and that fosters a sense of warmth wanting to be together...however, beware of touchiness with that...composite sun-Mercury can start insisting on full agreement with everything and overreact when the two people don't see perfectly eye to eye.
That's all for now...I hope others chime in!
Good luck
