I use freehost exclusively. I have it down to an artform. I do show pussy and cock but I don't show penetration. I think Lensmans's right about surfer having to pay but I don't think surfer is gonna come to my site if he can't see any pussy. I just lay off on the hardcore pics. If surfer wants penetration he can pay for a membership or a video.
I also have alot of free pics but I compress the thumbs and I put up alot of advertising. I think 20 pics with 1 banner is alot worse than 56 pics with 12 banners.
here's an example of how its done...son.
