Doctor warns against popular sex act which could increase your risk of nasty infections

Doctors have issued a warning for people who like to have sex outside of the bedroom, as one common place could lead to 'infection'.

Spicing up your sex life from time to time is healthy to keep the spark alive in a relationship.

Perhaps you and your partner are feeling spontaneous, and decide to take bedroom antics to a different room in the house.

The second most comfortable place is arguably the sofa - but it could be bad news for those who enjoy a bit of action in the living room.

NHS GP Dr Hana Patel has warned that sofa sex might not be all that safe, warning couples of the 'risks' involved.

Cleanliness is vital for any great sex life, but it turns out that the couch isn't as clean as you might think.

Talking to the Daily Mail, the expert said: "One example of potential harm is an increased risk of bacterial infections due to sofas often not being cleaned as thoroughly and easily as your bedding."

Limited research has shown that the soft furnishings we find around the house, including sofas, fabric-covered chairs, and more, can act as a breeding ground for bacteria.

Fabrics such as cotton, nylon, and polyester, as well as some plastics, can harbour the pesky bugs more than other materials.

A common infection that can be developed from sex is a Urinary Tract Infection (UTI), which causes a burning sensation when peeing.

Women have a greater risk of developing UTIs compared to men, as they have a shorter space between the urethra - the tube that takes urine out the body - and the anus.

Having sex on the sofa could increase a woman's chances of developing a UTI after sex, due to the likelihood that there is more bacteria lurking.

Another risk is painful skin, according to sex and relationships coach Gemma Nice.

Also talking to the Daily Mail, she said: "Towels and blankets can also help keep your skin protected.

"Especially if your sofa is made from harsh material or leather.

"It's best to have a splash blanket or some towels down to be on the safe side, or at least have some kitchen roll or tissue next to you."

According to a survey, 97 percent of Brits admitted to having sex on their sofa at least once - so it's important to be aware of the risks involved.
