Health experts have warned against wearing condoms during sex, with more than a third of UK couples failing to have sex after the first time.
The survey by the Royal College of Paediatrics and Child Health (RCPCH) found that only a third had sex after having sex with someone new, with only 8% of people admitting to having sex more than twice, or having sex a few times.
In a statement, the RCPCH said that a lack of condom use is linked to a range of sexually transmitted infections, including chlamydia, gonorrhoea and syphilis.
“People who have sex more often or without condoms are more likely to be sexually active and have more STIs,” the statement read.
“These include chlamydial infections, gonorrhea, and syphillis.”
The findings came as a new report into the risks of sexually active men and women revealed that more than one in three men in the country had unprotected sex in the previous month, and nearly half of all men who have unprotected sex say they did so with someone they met online.
The report, released by the Office of National Statistics, found that about 12% of UK men and 6% of women had sex with somebody they met via a dating website, in the past 12 months.
The researchers found that nearly three in four people had had sex more frequently or a few more times in the 12 months before the survey, compared to just over half of the people who had sex at least once in the year before.
There were also signs of increased risk of STIs in men, with the RCPHC finding that about a quarter of men had tested positive for chlamymosiomeres, the virus that causes gonorhoea, gonococcal meningitis and syphiomeres.
The study also found that people who have tested positive to chlamydomonas virus (CMV) were more likely than their peers to have had unprotected vaginal sex, and that people with HIV/AIDs had an increased risk to have unprotected vaginal and anal sex.
The RCPCHL also found a link between unprotected sex and an increased chance of cervical cancer in women.
“It is important to stress that cervical cancer is not the only cause of low sexual satisfaction, with many women also reporting difficulty with orgasm, partner-related anxiety, and feeling anxious around sexual activity,” the RCPAH said.
The research was published in the Royal Journal of Medicine, and is based on data from the 2011 National Survey of Sexual Attitudes and Lifestyles.
It also found the number of sexually experienced women in the United Kingdom had risen to 17.5 million, compared with 18.4 million in 2011.
The number of sexual partners in the last 12 months has risen to almost a quarter, with one in five women having sex at some point in their life.
It comes after a new survey of women aged 18 to 24 showed a higher than expected increase in condom use in this age group.
The Royal College said condom use was associated with fewer infections and the health risks associated with STIs, such as chlamypogenis, which can lead to infertility and can lead the virus to develop into cervical cancer.
“While condom use remains a highly effective and effective tool for preventing STIs for many, the evidence suggests that it may also increase the risk of cervical and other cancers,” the Royal Society of Medicine said in a statement.
“The use of condoms is a matter of choice and, if taken, is not always advisable.”
In 2015, the number for sexually experienced adults in the population rose by more than 15% to 1.1 million, with just over two-thirds of women having been sexually active in the preceding 12 months, the Royal Colleges research said.
“In recent years, we have seen a significant increase in the number and proportion of sexually and sexually experienced people in the community, particularly in the working-age population,” it said.
“The rising numbers of sexually informed individuals in our communities are a clear indication of the health benefits of the practice.”
