I agree, I think Virgo is one of the best stabilising energies for dealing with Pluto, especially Pluto and Mars.
I certainly wouldn't say we need to have kinky sex to 'keep things interesting', that's just the way our sex manifests. It's mostly really powerful. The freakiness comes from both our sexual tastes coming together as one. I also feel that since I'm Mars square Uranus Natally, with Uranus in the 8th, and everything sexually I bring
to his chart, I really being out a side of him he didn't even know existed.
Also I have a lot of strong Pluto aspects natally, and Pluto is the most prominent planet in my natal chart, so all the hard aspects between both our Pluto's and our personal planets brings out a lot of the plutonic issues I suffer with personally. I have Pluto conjunct Dsc in Scorp. I'm really possessive but I have a Virgo sun so you'd never know. I have Venus and moon in Leo too so my sexual and emotional behaviour is quite princessy, his Mars and moon are in Leo though, so he's quite the same (kingly, rather than princessy)
our moons are conjunct by one degree. There's a lot to our relationship, so much bad and so much good. It's exhausting and amazing all at once
