I think he means, there are some people whose fetish completely controls their lives, they think about all day long, it becomes all consuming.
I don't know if that's sad or not...I don't mean that in any kind of a mean way, but sad in that that person may miss out on life otherwise.
Some people want a life like this, and I'm not one to judge - SHIT, look how many people live their lives to watch sports, Reality TV, Daytime soaps, etc.....
I have friends who talk about politics ALL THE DAMN TIME. Like, they post to Facebook literally 5 times a day, every day, politics, religion, politics politics politics....
In that case, thinking about tickling all day long seems MUCH better!!
In my case, my tickling world is in my head, or on this site.
I've yet to meet another human who has a tickling fetish, or any fetish for that matter that I know of.
I've met two who MAYYYBE have one, but they could just like the occasional tickle her and there, I never asked, and won't because they're not in my life anymore.
(One basically is, but I only see him maybe once a year in the grocery store....)
I WISH I had a pretty woman who had a tickling fetish, it'd be like winning the lottery, and the big one, not them local lotteries!
My life is work, look for better work, sleep, cut the grass, pay down debt, etc. Very little joy to be had all around, except when the big movies come around, like Avengers 2 next summer....
