I wonder if it would help, if the sidebar with the "latest photo" was either disabled by default or it was made to be known that it can be disabled. While I myself am not offended by erotic images, even then I'd prefer not to see them without my own consent. Browsing an art gallery can be understood to be such consent, but just reading a forum not -- at least not in my opinion.
Regardless, I agree that there should space for erotic art in the gallery on this site. On the other hand, there should also be space for those people who for different reasons do not want to see such imagery and they should have that space without being called with derogatory names. I hope this site can be for those who are interested in analog photography, what ever their values, religion, ethnicity etc.
