Having sex can end up causing more pain than expected - researchers have found about 18 million Britons have injured themselves during or after a romp.
Pulled muscles followed by back injuries, carpet burns and bruised elbows and knees are some of the most common complaints, reports The Daily Express.
Boffins found the bedroom to be only the fifth most dangerous place to have sex.
The stairs came second in the danger list, followed by the car and the shower.
One in ten people or their partner fell off the bed. One in 50 toppled off the washing machine, according to the poll of 1,000 adults by phonepiggybank.com.
Some got hurt making love in the loo, or in a cupboard at work.
Two per cent of the total polled were left with broken bones after sex.
