I find it hard to believe
Well, that's your problem, not ours.
I've gotten models off of Craigslist, Instagram, through referrals from friends, producers, and former models, even here on the TMF. I've even had people approach
me to be in videos because they'd heard of what I do.
And with the exception of Instagram, a lot of those models - especially the ones from Craigslist - were not professional fetish models, they were just typical gal-off-the-street types who thought it would be a fun thing to do. I worked with
my best friend's sister, purely because she saw my business card and said "I need to meet this guy".
I'm going to let you in on a little secret. 99.99% of the stuff people say about the type of women who agree to do tickling videos is complete and utter bullshit, and the other 0.01% is debatable.
And not all of us expect people to "strip down to their underwear", so there's that.
