They must have thought it brilliant. They degayed him and virginised her with one article.
It's actually bad PR for both:
Taylor seems both clueless and imature for a 23 years old, eternally stuck in teenagehood;
Harry is presented as a horndog who wants to pressure a girl into sex which is very bad from a young teenager point of view.
Talking about sex is always a bad idea anyway with young fanbases... and in the future, they will both have to attempt to attract older fans too who might have a very different view on that same topic. This angle is the worse idea ever IMO.
