Unsafe Fetishes: Do You Have Any?

I've always been turned on by hot wax being poured on girls in porn and wanted to try it but my bf is afraid he will burn me with the wax so he will not try it.

I think this depends a lot on what one considers "Unsafe"
Many fetishes CAN become unsafe if done improperly and/or without the right knowledge of how to do them well. You wouldn't want to get into serious rope bondage without knowledge of all the little safety precautions that come along with it, for example.
As for me, no.
My current play partner is pretty darn knowledgeable, so anything we do that could be dangerous in certain situations is perfectly safe between us

no no no. i am always safe
