Open Question: Is acting out a harmless fetish unfaithful?

[feedcrawler]

Say i have a foot fetish, and I'm in a long distance relationship... well, if I'm friends with other girls, would it be unfaithful to my lover if i engaged in fetish related activities with my friends? I don't mean anything sexual, of course, more like smelling her shoes or socks, or the like. Something harmless like that isn't that bad, is it? (And yes, i know this is weird, consider it hypothetical)
