Uh... Well, this is a very controversial topic. But here's my take on this.
This site is a "softcore" site, the owner always make this precision everytime someone ***** on the dull content. "Softcore" is porn, porn have the only objective to sell entertainment that provide sexual arousal in the viewer. Softcore boundaries are very debatable, but fingering briefly and mild masturbation are as far as it should go.
To me it's ok if they don't want to go borderline, but the sexual explicit behaviour most be really explicit, with that i mean full detailed nudity, a perfect view of everything, with enough time of exposure to enjoy it, and presented in a way that is hot, deliberated, lascivious and thrilling. And this features are not beyond softcore standards.
As i said before, they can deliver a softcore product that is hot, with good quality and exciting, or deliver a bad softcore product that is dull, poorly realized, and uninteresting to the viewer. I prefer the first. ;)
