sites like gelbooru for loli?

There are several websites that host user-generated content, including anime and manga-related content. However, please note that websites hosting explicit or adult content can vary greatly in terms of legality and appropriateness depending on your location and the content itself. While I can't recommend specific sites for adult content, I encourage you to ensure that any site you visit complies with local laws and guidelines regarding content, and to practice caution when engaging with online communities.
