It depends what you mean by “think twice”. It could be that you’re saying that you should not be reckless - to be extra sure you both have the same expectations from the encounter, that you both consent, that neither one of you is beyond the point of being able to properly give that consent (ie you and partner aren’t completely intoxicated), that nobody else’s feelings are going to be hurt and a few other things, that you use protection etc … But if you mean that people shouldn’t ever be having one night stands, yeah I think that is a little more conservative than the average person. In this context though, the Daily Star means that this is something people might not even consider is illegal, having not grown up or otherwise lived in a strictly religious state
