I've spent a lot of time searching the freebies to find out exactly what I like and noticed that in the photos I prefer to see these beautiful girls with a soft cock.
Maybe I feel intimidated by someone waving ten inches of pork sword at me when we've only just met!
But to balance it out - let's say I like to see the girl partially clothed (bikini or short skirt and bra) then naked and soft and finally standing proud for the before and after pictures.
It's a different matter when it's a porn pic and there's some action going on of course.

i like to see them soft. seeing a flaccid cock turns me on cuz i wanna make it hard!

Rock hard. Stiff as a rod. Red and swollen.

Hard
 

A nice long hard cock, it's makes it so much easier to penetrate and creampie the ass :turnon::turnon::coupling:

I like them both but if I had to pick one I would say soft

hard
 

The harder the better:turnon: unless it's covered in sexy panties:turnon: then it's ok.:yes:
