Ahá!, good question friends.
- Nudity yes, genitaly yes (I don't think genitalia could be a problem, but I could be dead wrong and banned forever).
The thing is, human mind works in strange ways, it's more erotic and peeps get turned on more with partial nudity, so for example: a female in a sexy pose with a cleverly placed object covering her genitalia it's generally more arousing than showing the full thing. So there's that to consider. You can show genitalia but for a better effect on the reader, if eroticism is what u seek, covering a little would make the crowd go nuts.
Sexual nudity, that's a no, Tapastic guidelines say no no.
Sadly, hentai no.
Line between erotich and porn: Mmm, a girl eating a banana can be erotic, and girl puttin' the banana in her P@#$" it's porn.
A man nude with a glass bottle covering his manhood it's erotic, a man puttin' the glass bottle in another man's a"" it's porn.
So explicit representation of the sexual act are generally considered as porn.
Homosexience here it's a fine example of a comic that walks on this fine line, it's erotic, yes, it's sexual, yes, but it never goes full hardcore.
- Ero vs Porn. Round 1: A guy is cuming:
Ecchi/erotic: Shot of the guy's face blushing and then a volcano erupting.
Porn: Shot of the penis ejaculating.
So erotic could be hinting the act, porn could be straight showing it.
Phew I hope this helps, this is my little take on it.
