It can be both. If I'm in love with the person, I'd probably indulge both on a regular basis, and if SHE had the tickle fetish also, it'd be even better!
Both, like, sometimes I'd love to tickle her while she had a sheer black nighty in suntan colored pantyhose or stockings......and other times just a quick tickle after she tells me a bad joke.
Redheads are hot, by the way, in case you need your day made even better!
The ONLY person I know who has any kind of a fetish, is a friend who has a redhead fetish.
Unlike most here, though, he happily BRAGS about it, even when important people are around!
