That depends on what your "friends" fetish is. It must have been pretty bad to have a reaction like that since i'm sure they get weirdos all the time.
If i was something along the line of "i want to tie you up and spank you" then i'm sure your fine.
If it was something like "i want to cut you up and scatter you around the country and kill everyone you know" then you're probably in a bit more trouble for being threatening.
Highly doubt they called the police though, it'd be more work than needed, they probably just blocked your number so you couldn't call ever again.
