According to this definition and also according to all other definitions I heard so far I am sure that most men who like long hair do not have a fetish. Fetishism in its extreme may present itself in the fact that the man can't be satisfied anymore by a woman, but needs to be alone with the object of desire to get sexual satisfaction. Often these men are even scared to touch a woman. The police found out later that he built himself a bed of hair to sleep in. I do not have the intention to present fetishism as harmless.
Fetishism does appear in many different shades.
Secretly stroking a ladies hair while standing behind her in the subway is certainly an indication and shall be followed up. Covering male hair as well means nearly double work. As this site is done free of charge and in my spare time, I had to reduce my efforts. I decided for the subject of female hair, which pleases me much more than male long hair. Having a quite conservative mind I also rarely find men with long hair who appear attractive to me.
