Consultations at sexual health clinics reached 4.5 million last year – up from 2.9 million in 2013 – according to latest figures from the UK Health Security Agency.
The LGA said these show sexual health services in England are under unprecedented pressure, reinforcing its calls for a long-term national sexual health strategy.
It warns that the system is struggling to keep pace with soaring demand, leading to potentially longer waits and reduced access to timely care.
The LGA is calling for a 10-year sexual health strategy to tackle rising infection rates and ensure services are sustainably funded and properly resourced for the future.
Cllr David Fothergill, Chairman of the LGA’s Community Wellbeing Board, said: “These statistics show that local sexual health services are grappling with significant increases in demand.
“Without adequate investment, people will face growing barriers to accessing expert, timely care.
“Councils have worked hard to promote regular testing and early detection, which are vital for preventing the spread of infections and improving public health outcomes.
“Investing in sexual health services not only reduces long-term illness and unplanned pregnancies but also eases pressure on the NHS and enhances the wellbeing of our communities.”
