Those behind the demonstration outside Parliament on Friday morning say around 250 people turned up to voice their objections but Ms Dorries said she thought it was only 100.
The Mid-Bedfordshire MP’s bill was due for a second hearing but was eighth on the list and didn’t go ahead.
Campaigners disagreed with the bill which would have made it a requirement for schools to provide certain additional sex education to girls aged between 13-16 including the benefits of abstinence.
Organiser of the demo Beth Granter said: “The bill would have meant that some schools that don’t currently provide any sex education, for example religious schools, could end up just teaching abstinence.”
But Ms Dorries said the bill had been misrepresented adding: “They have been saying I am putting forward an abstinence only bill but it’s about trying to empower young girls.”
She said when you propose a bill the hard copy gets printed the night before and because she knew it was eighth on the list she told them not to print it as it would have cost around £800.
She added: “It’ll have to retable now but it might become part of another bill as I’ve got a number going through.”
