Casual sex is a controversial issue. Whilst some believe it to be the best way to spend a Saturday night, others condemn the morality of it as well as the physical and psychological dangers. Generally, casual sex has a bit of a bad reputation and that reputation can easily stick to those who regularly partake in it. That said, a great number of people find themselves involved with casual sex at one point in their lives. In fact, around 80% of undergraduate students admit to having casual sex[1], and by the age of 25, around 70% of the population will have ‘hooked up’ at least once[2]. With such a large amount of the population having had some experience of casual sex, even on a small scale, it seems bizarre that there should be a negative feeling around it, but perhaps there are reasons for that. Putting aside the more obvious ones, such as the risk of sexually transmitted diseases or unwanted pregnancies, many are beginning to question whether casual sex is actually bad for your wellbeing.
