I always wonder about others, but slightly on topic...
I tend to spend a fair bit of time in Kowloon (in just one or two night stays) and till recently have had a regular friend there who has always had me try (with her) something different each trip. Her more recent has involved latex (though its been plastic rather than rubber). Some of the other I haven't been too enthralled with though.
So what's your kink preferred kink ?
