A new report predicts that one in five women will have unprotected drunken sex unprotected drunken sex on vacation this summer.

Investigators looking into the sexual habits of women found that their "devil may care" attitude about sex happens the moment they arrive at their vacation destination.

The study, which consisted of 2,000 women who filled out questionnaires online, also found that one in ten women will have unprotected sex on vacation with a complete stranger or someone they met during their break.

Women participating in the study, conducted pharmacy site DrFox.co.uk, found that four out of ten single women admit that they are significantly more likely to have unprotected sex when they're on foreign soil, and 13 percent of women in their 30s are also planning to have sex without contraception during their summer holidays.

"It’s concerning that many women are not practicing safe sex," website founder Dr. Tony Steele said, according to Daily Mail. "What is more concerning is that people are actually planning on having sex without a condom whilst on holiday."

"People you meet on holiday are complete strangers so you know virtually nothing about them - having sex without contraception is a sure fire way of increasing your chances of contracting an STI," he said. "Whether on home soil or thousands of miles away women whether they are 18 or 55 need to be practicing safe sex and using condoms."

The study also revealed that a third of the women questioned admit to being swept up in the moment and forget about using condoms and one in five say that they trust that their partners will not give them an infection.

An alarming 18 percent of single ladies also said that they are often too drunk to use contraception, 12 percent say that contraception is always readily available when it's needed and eight percent admit that they just don't like using condoms.

The study revealed that despite being older and wiser, 10 percent of women over the age of 30 still feel embarrassed about bringing up the subject of using protection with a new partner.

Investigators found that women between the ages of 30 and 40 years old were most likely to have been infected by a sexually transmitted infection followed by girls between the ages of 18 and 29.

Overall, the survey found that the average single woman has had unprotected sex 11 times with a total of four different men.

While women between the ages of 30 and 40 were most likely to take the morning after pill, the latest findings show that women over the age of 30 report getting worse at using contraception as they got older.

Nearly a third of women in their 30's say that the younger generations have grown up in a world where education about sex and sexually transmitted infection is more accessible, and it shows, with one in five women between the ages of 30 and 40 to report having had unsafe sex in the last three months compared to 15 percent of women in their teens and twenties.

However, women of all ages surveyed agreed that contraception should be a responsibility that is equally shared between both men and women.
