Millions of Brits would be embarrassed for fear of looking silly, stupid, or naughty if others saw their internet search history.
A study of 2,000 adults found 17 percent would feel ashamed if friends and family knew what they looked up online, with 40 percent of these worrying about sharing the daft thoughts they have.
A further 4 in 10 don't want others to see their inappropriate history, while 37 percent say it reveals a side of them they don't want to share.
Others would be left red-faced if people knew of their mental health struggles (26 percent), their lack of knowledge (25 percent), or their physical problems (15 percent).

Exactly half of those who don't want to share their internet habits would be most shy of showing their parents.
A spokesperson for ExpressVPN, which commissioned the research, said: "The internet has become our best friend, but it's important that we treat it with care.
"Our research shows a large part of the country is more open with the internet than they are their own family, for one reason or the other.
"People deserve privacy online, including from snooping corporations, and so shouldn't have to deal with the worry of having their search history exposed."

While parents ranked as the people Brits would be most embarrassed about seeing their unfiltered search history, partners followed closely behind for 40 percent.
The research, carried out by OnePoll.com, revealed 38 percent would be most embarrassed if their friends saw what they had searched for online.
Meanwhile, colleagues followed behind at 20 percent.
Among the most common topics the nation would rather search for, as opposed to asking their friends or family, include finding out the meaning of certain words or wanting to know weight or height conversions (30 percent, respectively), while a fifth would rather turn to the internet for recipes (22 percent).

The nation still values advice from friends and family when it comes to relationships, as only 1 in 50 look online over asking their nearest and dearest, and just 1 in 10 will search for advice about sex, while a mere 5 percent will research how to date.
The main reasons cited for choosing the digital sphere over loved ones include how quick it is to search online (57 percent), having confidence in getting the right answer (41 percent) and the internet knowing more than friends or family (39 percent).
A spokesperson for ExpressVPN added: "Every day, millions of internet users are giving big companies the ability to look at what they're doing online - and they don't even know it.
"Using a VPN can be a useful tool to ensure companies can't see, log, or sell records of your activity online, such as what websites you are connecting to or apps you are using.
"By taking control of what we let others see about our online behavior, users are taking power back into their own hands, quickly and effectively."
