Almost a sixth of British people think gay sex should be illegal, according to a new survey.

The survey of British sexual behaviour, which used a sample of 1,052 adults in the UK, was undertaken by the Observer.

The highest figures came from the South East and London, which saw 21% say they thought gay sex should be illegal.

Despite being seemingly a high figure, the percentage has dropped considerably from 24% since the last time the survey was carried out, in 2008.

When asked ‘how would you define your sexuality?, 4% said gay, 4% said bisexual and 92% said straight.

Also, the percentage of people in the UK who think same-sex marriage should be legal has risen from 53% to 63%, and 61% of people think gay and lesbian couples should be allowed to adopt children.

Overall, the average number of times people have sex each month has dropped considerably, due to a hike in the number of people who don’t have sex at all.

20% of men said they were unhappy with their penis size, and the percentage of men happy with their size dropped from 86% back in 2008, to 79% in 2014.
