I had a look at other sexy knicker reviews - women reviewers tend to give a factual post, commenting on fit and material. I haven’t seen one review from a woman that reads like they have a fetish or are turned on by wearing the pants.
As M&S allow men in their changing rooms and given the social media fetish that many TW appear to have of taking aroused selfies in these unisex changing rooms, I now give them a miss. I’d like to think that M&S have seen a downward turn on sales given that they value their target customers so little.
