One should understand that having a fetish is not abnormal, everyone has fetishes, but it's just that we nurture them within set limits. There are different degrees of fetishes that range from mild to extreme." He further goes to explain that if, "one is attracted to blondes that's one thing, but if you are unable to get aroused unless you're with a blonde, then you likely have a fetish". Fetish can be particular from individual to individual. They fall under three categories - media, form and animate. In the first category, a fetish is developed for a particular material with which one is obsessed with such as rubber, leather, latex, and silk. But with form fetish, it's the shape of the object that gives a high such as a woman's stilettoes, knee-high boots or lingerie. On the other hand, body parts like feet, hair, buttocks or breast are called "animate" fetishes. It's important to understand that fetish preferences differ from individual to individual. "Generally it's seen that a fetish is accompanied with certain feelings of guilt or shame. Try and seek other people who share the same sexual desires and practice it," opines sex expert Dev Karan. Some of the top fetishes that couples seem to posses: Body piercing : Ask the younger lot and body piercing seems to be a top fetish amongst them. Interior designer Priya Gill says, "A pierced body turns me on. It can be anything from belly buttons to tongues and eyebrows. Everyone should have at least one body piercing in "that" place to create a feeling of arousal". Dr Rajan Bhonsle puts in a word of caution saying, "One should be very careful as to where he has got the piercing done from. The area should be free from any kind of infection and kept clean. One should also try to sterilise the ornament they are wearing". Latex fetish : Men love material. The "bad" and "naughty" are always attractive. Model Rahul Mehra states, "My girlfriend's wardrobe has loads of garments in latex and leather. It's quite a turn on for me and gives me pleasure, making me more innovative in bed". Watching a woman move around in anything tight and shiny is a tease in itself. Dr Shekhar Shah says, "The hygiene factor is very important. Sweat blisters must be avoided. Signature stockings are common with women. Latex gear also acts a catalyst. Fetishes are, most of the times related to some object or palpable thing".
