Pretty pictures are great but it's personality that's absolutely essential for me.
It's not yet worked out for me to meet any of them, but the pics+personality appeal of @Mikegaite, @Russ & @Eric Hassan have definitely put each of them on my bucket (f*cket?) list... Links to social-media presence are also a big plus, as are non-explicit home videos. And I love it when a gent lists a multi-hour fee structure.
I do prefer face pics, though a multi-faceted faceless profile (like that of RomanLA) can totally work for me.
My turn offs tend to be sloppy inconsistencies within the profile info, flipping the bird, and all/only/too-many porn-studio shots/videos.
