Yes, that is okay.
Things that need to be censored are as follows (based upon my communications with staff last time I had to fix up my comic to keep it on the site):
- Erect penises
- Lubricated vaginas and anuses (or any genitalia displayed in an erotic manner)
- Penetration of anus or vagina. Object, penis or finger does not matter; all needs to be censored.
- Oral sex
Things that do not need to be censored
- Non sexual nudity of any kind. So if you have an unaroused character shown nude, that is okay. I will divide this point by two since my understanding is that it also comes in levels:
- Below the waist nudity in non sexual display is allowed but requires you to mark it as Mature/NSFW content. It doesn't require censorship however.
Exception: Butts where you don't see the genitalia, displayed in a comedic manner do not appear to require a Mature content marking.
- Above the waist nudity is allowed and does not require Mature content/NSFW mark at all. Gender/sex of the person displayed doesn't matter.
Obvious exception to all of the above: Displaying children in a sexual manner is not allowed. Since Tapas is US based, I do believe the line is drawn at 18, regardless of what the age of consent is in the author's country.
No self promo intended; linking a mature scene from my comic so you can get an example of how these rules can be applied: https://tapas.io/episode/1096281
