Sexual fetishes have often been explored on Netflix's Sex Education, particularly surrounding the character of Lily (played by Tanya Reynolds). Lily's character has an interest in aliens and otherworldly beings, which she tends to incorporate into her sex life.
The idea of fetishes has long been considered weird or abnormal, but actually, they're more common than we think, and it's absolutely OK to have one or many. According to The Independent, research from the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5) shows sexual interests can fall into two categories: normal (normophilic) and anomalous (paraphilic). Of all the paraphilic categories listed, a study revealed that "Nearly half of the [surveyed] sample expressed interest in at least one paraphilic category, and approximately one-third had had experience with such a practice at least once."
Basically, it seems that most people will (at some point) express an interest in fetish-like sexual activity, and a number of us will even try it out.
