Is It Right for You? Depending on the context, casual sex may be celebrated, relished, derided, envied, or stigmatized. Some people consider the activity in a serious way, evaluating all the possible ramifications emotionally and physically along with the potential benefits and drawbacks when thinking about having casual sex. Others take the idea of casual sex, well, a bit more casually. That said, many people have strong opinions about whether or not it's a good idea, although these attitudes tend to shift as life circumstances—and relationship statuses —change.
