You can change your visibility toggles in this page if you don't want to see nudity: https://toyhou.se/~account/display
However Nudity doesn't always imply sexual (see: artistic nudity, like statues you can find in gardens and art museums), and doesn't need a 18+ filter in that case. If the nudity is sexual in nature, it needs the sexual content toggle. That's why it's separate.

1.2. Content Filters
Toyhou.se provides the following content filters for categorisation of artwork:
- Nudity
- Any depiction of bare genitalia on humanoid figures, with the inclusion of visible labia or penis sheaths. This does not include nipples or bare butts.
- Mild Sexual Content
- Content that implies sexual activity, including but not limited to clothed but visible sexual arousement, fetish content or presence of toys or props designed for sexual use.
- This also includes depictions of nipples, genitalia, or buttocks (clothed or bare) where they are the primary focus of the image, disproportionately detailed compared to the rest of the image, or are being fondled or otherwise interacted with in a way to bring attention to them.
- Explicit Sexual Content
- Explicit depictions of sex or masturbation, including any visible depiction of sexually aroused genitalia.
- Gore
- Any depiction of internal organs, viscera, visibly broken bones, or freshly severed limbs or body parts.
- Photos, photo-realistic artwork, or highly detailed images have a lower requirement, and should be flagged if they contain a large amount of blood or open wounds.
- Sensitive Content
- This is an unmoderated filter which is used according to user preferences in cases where they would prefer for the thumbnail to not show up immediately in their character's gallery, or would otherwise like to provide a warning for their viewers. For some users this may include images with nipples, for others this may be substance abuse or self harm, etc. Images containing Sensitive Content will always be hidden behind a tag regardless of the viewer's filter settings.
Submission of material containing Explicit Sexual Content without being appropriately flagged (in the case of images) or containing a warning in the title (in the case of forum threads or bulletins) may result in your content being moderated or removed by site staff. Repetitive and intentional submission of unflagged material containing Explicit Sexual Content will result in warnings or account bans depending on severity and intent. Please be considerate of the users around you.
Material containing Nudity, Mild Sexual Content or Gore without an appropriate flag may have flags added for you by site staff without prior warning.
