Temp play substances?

What kind of things do you put on the more sensitive regions of the body to get some interesting and borderline unbearable sensations?

I’ve experimented with toothpaste and tiger balm and the stinging sensation from the toothpaste I found the most fun!

Some of the lubricants with the sensation chemicals in them really are a nice change from the norm!

Vicks Vaporub gives a nice sensation rubbed on delicate bits.

I’ve never tried Vicks but I imagine it must be similar to tiger balm!
