The thread with the guy who tickles his 2 female roommates feet and unbeknownst to them gets off on it, reminded me of this thread. Only here we're talking about someone choosing their profession for the purpose of getting to tickle feet, so its a little more involved than the guy tickling his roommates.
First of all, there are people who have to change the discussion and say "yeah well what if he videotapes it or photographs it without your knowing? What about a dentist who feels up his patients while they're knocked out?" Let's keep this to the original scenario. A guy with a tickling fetish sees videos on youtube that young women take of their friends getting tickled half to death by little asian ladies giving them pedicures. So he decides "the little asian ladies aren't even trying to tickle them! They're just doing their job and it happens to tickle the girls. I'm going to become a pedicurist and do what the little asian ladies are doing." That's it. He doesn't photograph or videotape anyone without their knowledge. He doesn't do anything outside of his job description. He does his job the same way the little asian ladies do, does nothing different than they do, except that he's getting sexual gratification while he does it.
Okay, I will use myself as an example here. Let's say I have a doctor, and unbeknownst to me he happens to be gay. Its none of my business anyway, but lets say its totally unbeknownst to me. Let's say this doctor is not just any doctor who happens to be gay. He specifically became a doctor for the purpose of getting to examine men, because it excites him sexually. I'm sure he has much more attractive male patients than me, but maybe he likes obese hairy men, who knows? Ridiculous example, I know, but bear with me.
Anyway, this doctor also does not photograph or videotape me without my knowledge. He doesn't touch me in any way that is unnecessary for him to do his job. He is competent and always gives me the correct diagnosis and prescribes the correct treatment, if any. Now from my perspective, this doctor has served my purposes. I got the use that I needed to get out of him. He also, again unbeknownst to me, has gotten use out of me because he goes home and masturbates as he recalls examining me. Sorry, if I was physically attractive maybe this would be a bit more believable. But anyway we have been mutually useful to one another.
I think that's the point of all this. People serving their useful purpose. He does nothing unnecessary or outside of his job description. He just happens to have gotten into that profession with ulterior motives. But from my perspective, I got my proper use out of him, so I have no complaints. And neither would a woman getting a pedicure from a competent pedicurist who knows what he's doing and is good at his job. There's about a 0.000001% chance that the little asian ladies in the nail salon are intentionally tickling those young women. Its just part of what they do, unless every ticklish pedicure ever posted on youtube was done by an incompetent pedicurist. Otherwise, the competent pedicurist who got into the profession with ulterior motives has from the client's perspective, served his useful purpose and unbeknownst to her, she has served her useful purpose (for the pedicurist) as well. But he provided the service she paid for in a competent manner, so she has no grounds to complain. I think I've explained this side of the argument as well as anyone could.
