Some people aren't sure if they even have a fetish while others think that their fetishes are abnormal. So what is a fetish? A fetish is a condition in which someone is sexually fixated on an inanimate object, such as high heels or lingerie, or a nongenital body part, and has to touch, rub, smell, or see the object in order to become aroused and climax.
You need that specific something for sexual gratification. When you masturbate, you have to either fantasize about that object or have that object with you. Even if you have sex with a partner, you still need to fantasize about that object or have it present.
For instance, if you're attracted to a brunette, that's one thing, but if you are unable to get aroused unless you're with a brunette, then you likely have a fetish.
Of course, lots of men - and women - are turned on by various parts of the body and things like sexy underwear. But, they don't need them to become aroused, which is what separates an attraction from a fetish.
As long as a person with a fetish (called a fetishist) is still interested in having intimate relations, and he has an understanding and willing partner, the object of desire can be incorporated into their sexual repertoire.A look at different degrees of a fetish Fetishism exists on a continuum of extremes. Yes, some hard-core leather fetishists can't get off without leather. They may be intensely fascinated with collecting leather clothing or may find themselves overwhelmingly -- and sometimes uncontrollably -- aroused by seeing someone wearing leather in public. Others, on the other hand, have a much milder relationship to their fetish. They find that leather adds a powerful emotional, sensual or psychological punch to their sex life. They like having leather around, but they sometimes enjoy non-leather sex too. The lowest-intensity fetishist might occasionally use leather to add extra spice to an otherwise relatively ordinary sex life.
