you can to the me tab and set your fetishes if you're talking about like watersports and such think you'll have to go back to main menu and enable it there in options
in the me tab it should be in encounters where you can edit your fetishes you like or not though think it just reduces the chance of others doing it to you so you might have others still do to you anyway on a low chance though but idk that i have all of them set to like so i wouldn't know
