Women have sex without protection if they believe they can form relationships

Women who think about spending the night with someone new are more likely to have vulnerable sex if they think he's potentially the person they can connect to.

They will also have vulnerable sex with a person if they think they know him, a recent study has been found.

More than 200,000 women a year in England have been diagnosed with a sexually transmitted infection like clamidia or herpes.

Women in general are more likely to say that we will not have sex without a condom. But a new study, involving 177 women, has found that they can be exempted from harming themselves if they seek relationships and have a sense of familiarity with the man in question.
