The athletic V taper: shoulder-to-waist ratio is just an undeniable attractor to me. So are just the presence of muscular arms, chest, shoulders, traps and thighs etc.
But even with this strong impulse, I am also easily attracted to the 'dad bod' as well. I think I deal with gut weight the best. I like body hair far more than a shaved bare look.
Faces are super important. I find that I can usually tell from just a tiny thumbnail that the man's face is something I respond well too. I can't really think of what traits specifically. It's more just a yay/nay thing. It's a very fast judgement that's barely conscious.
In terms of personality - I highly prize self knowledge and self control - as I've found that lacking self perception and poor inhibitory skills predict the types of conflict that annoy me the most (bad actions with bad justifications).
