So, none are Sexual Fetishes....one is a Habit and one is borderline habit (irrational behaviour).
A Fetish, can actually be anything that you have a particularly strong liking for or appreciate a great deal.
A Sexual Fetish, is obviously, when the thing you like so much, happens to be of a sexual nature.
So, not all Fetishes are sexual...not all the sexual ones are odd or dirty (if you really like asses, it's still a Fetish).
Further more...people like to use the word "Perverted" lots, when talking about sexual fetishes they don't care for...or even to use as a derogatory term for a person, for whatever reason...but, the fact is...that any person who has sex, for any other reason, than to conceive...is a pervert, end of.
