>>1272448Wait, wait, wait. You can't just clump cum in with the things that share the same category as dicks; they're just not the same thing. You see, cum is meshing itself into the framework of ecchi in the modern age. It's more of an accessory to the prose of a beautiful girl than it is a marking male attribute. Sure, semen comes out of a penis, but you don't normally immediately think that when you see it, plastered all over a girl. You just think "Oh, wow that's really hot! She's obviously had a fun time. I'm just going to go ahead and say that it's added a nice, appropriate flare to the picture." And that's good, since it's good to mix things up, every now and again.
Now, dicks. They're a completely different thing. You see, they take away from the sort of "pin-up model" aspect of ecchi, thus diluding it, once it's been turned into hentai, into just another type of porn. After a dick has been added, the picture can no longer be appreciated as part of the art of ecchi. Sure, it could still be considered art as hentai, but hey. Apples and oranges.
