Oy, what an interesting thread! Thanks for resurrecting, rory!
Now me, I'm a total energy addict. If somebody gives me good energies I am attracted to them, regardless of looks, age, gender, stuff like that. I think with Sweetheart we are such an excellent match because of my feminine/active energies complement his masculine/passive ones and vice versa, which with men doesn't happen often for me.
That being said, I do dig soft, chubby brunettes. Olivia Wilde would be almost too perfect if she weren't so underweight.
I often need one-on-one sex to determine for sure if our energies match (yet again, with the exception of Sweetheart). So for me, great attraction grows with sex, whereas struggling to make a sexual connection lessens initial attraction.
