Leeds is one of Britain's top spots for dogging and public sex.
The city had the eighth most 'sexy spots' of the UK cities surveyed by dating app Datingroo, which collated locations for dogging, cruising, hook-ups and outdoor sex.
Popular places for such encounters included Adel Woods and King Alfred's Fields, Moortown.
Other top spots for public hook-ups included the now demolished Leeds International Swimming Pool and the toilets of a certain supermarket.
A shopping centre in Sheffield was also a popular place for risky casual liaisons as were the grounds of Conisbrough Castle, South Yorkshire.
Datingroo's research shows almost 30,000 Brits have been searching for dogging locations in the last two months while there has been an 85% increase in people searching for outdoor hookup spots over the last year.
The last two weeks showed the highest number of dogging searches since summer, Datingroo said.
What is dogging?
Dogging is watching people having sex in a public or semi-public place.
There are theories as to where the term originates. One suggests it derives from 'going out to walk the dog', an excuse used by doggers for their dodgy activities.
Another suggests it originates from the verb 'to dog', i.e. to follow or track something.
Is public sex illegal?
This a legal grey area. There are a couple of legal clauses under which you can be prosecuted, such as 'outraging public decency'.
In a place where you have a reasonable expectation of privacy, it's unlikely you'd be prosecuted.
You could be prosecuted for watching someone have sex in public under the offence of voyeurism.
Sex in a public toilet is illegal.
