I'd hoped to avoid using Blogger because it's owned by Google, but it does seem like a better option. Plus I just noticed this in the terms of service for Weebly - These types of sites are not allowed on Weebly:
Adult: involving nudity in a sexual context, exposed genitalia or adult themes.
There are a couple of pictures that have "exposed genitalia" in them, though it was still kind of artistically done. Or at least I thought so.
You may run into issues at Blogger as well, though nothing major.
"As outlined in the Blogger Content Policy, adult content is permitted on Blogger; however, when adult content is flagged by users, we may show users a content warning page before they view flagged material to prevent people who don't want to see this material from stumbling on it accidentally. We feel that this is the best solution in order to maintain a safe online experience for users of all ages and to be a platform for the personal expression and creativity that has come to characterize Blogger and its users."
The services that would allow it (without issue or question) are probably ones you want to avoid anyway. I doubt what they are hosting is 'artistic'.
