Well i think they are legitimate. Sometimes there is just something in the "air" that cannot be explained away.
Is the fact that Capricorns solar "exaltation" in Mars,the reason why Sun-ruled Leo is so impressed with them?
Is Virgo's dignity in Mercury the reason why Uranus ruled Aquarius smiles at them so often?
And what is it about emotional Cancer that enjoys exaltation in Jupiter that fascinates the philosophical Sag so much?
But I also think that as people get older,they tend to want more "ease" in relating to their partner.
Is it possible that couples who started off bland or as friends(trines/conjunctions) start to enjoy their relationship in the later years?
Perhaps couples who started with great excitement and/or sexual attraction need to learn to make peace with each other-as time continues and things settle.Or let each other go?
As for me,I prefer sun-sun trines and sextiles to romantic relationships.It just "feels" right after a while.Can't explain it really.
Aries and Leo energize me. Aquarius and Libra complement me.
Libra especially gets romantic very quickly maybe due to the Venus-Jupiter respective ruler-ship? I can't say
I've learned from my experiences with Cancer and Taurus that despite the intense attraction,the in-conjunct relationship gets really CHALLENGING really FAST.
I want complete freedom to be myself(Sun) And trying to sensor myself to "keep it together" for the partnership- becomes less pressing in importance.
Taurus(though also Venus ruled)can find me foolish,embarrassing, playful and too candid The emotional turbulence of Cancer brings me anxiety
As parents and teachers- these signs are fine. As lovers- I am asking for trouble. More especially with Cancer.
