Pretty sure you can't "quit". More like hide it from someone. Take me for example. I had a few girlfriends who I told about my fetishes (feet & tickling). Needless to say they did not receive the news well, and the relationships tanked shortly thereafter. I went on about a 2 year dry spell, no girlfriend - nothing. I met this amazing woman at college, fell in love, and figured I better not screw it up. I didn't tell her about my fetishes. Turns out she has a HOT pair of feet, and it eats away at me EVERY DAY that I can't get near them. And of course now I would feel bad and guilty if I told her, since we've been married a little over a year. So do yourself a favor and tell your significant other before it gets too serious. If they're not down with what you like, you'll find someone who is. And never try to "quit" your fetish, it will only eat at you.
