You're a person who thinks nudity is hotting than clothing/partial clothing aren't you?
I'm a person who thinks a harem hero fucking his girls is hotter than a director fucking around with his audience, which is the only thing that ever comes out of TLR besides the doujins.
Power is the ultimate aphrodisiac. Money is power. Technically-non-pornographic shows can be distributed by more mainstream channels than pornagraphic shows, even if those channels are not normal TV hours. Distribution by more mainstream channels makes more money, since that way it can reach a wider audience and at least reduces shame. Therefore, it is sexier (for the people making it) to make it technically nonpornographic.
Your previous statement makes no sense whatsoever given that there's nothing even vaguely erotic about Momo being force-fed a popsicle. Meanwhile in Tsunkenland we have Rito actually fucking people and being a dominant alpha badass instead of a useless waste of flesh like the other 95% of harem protagonists.
