The ex-Crimewatch host was speaking at The Telegraph Hay Festival where he made the comments.
"We're all inquisitive," Ross was quoted as saying by the newspaper.
"I had never seen, until I started working on Crimewatch, child pornography."
He added: "I think if someone came to me and said, 'Would you like to see what all the fuss is about?', I'm sorry, I probably would say yes."
Of a reported study which found that web users clicked links to extreme pornography they had not searched for, he added: "Does this tell us that we're all awful? I think not."
Ross, who attracted criticism last month for his comments that for some rape victims "rape isn't always rape", also claimed that people of different nationalities were more suited to committing different types of crime.
"We're very bad pickpockets in this country," said Ross.
"We're incredibly good at car crime. It does seem that contact crimes of the sort people don't like, such as mugging, are specifically of some communities from the West Indies."
He added: "Does that mean they're worse than us?
"No. Does that mean they're less moral, than us? No. It just means they're not very good at pick pocketing, they do this sort of crime."
