The article highlights a debate about a study on women's underwear conducted by Christian Jantzen and Per Østergaard from universities in Denmark. Dee Amy-Chinn of Oxford Brookes University in England has argued that the assertion in the study that wearing erotic underwear has an obvious link with sex is an exaggeration. However, Jantzen and Østergaard have defended that their study has found that the common motives in buying such apparel is self-gratification which also imply acts of auto-sex.
