Not sure what you mean by temps and materials?

Ice or hot candle wax comes first to my mind.
Leather and latex comes first to my mind about materials.

…only by myself using porn and a vibrator.

So I’ll assume that they have tried a vibrator on you.

Cool!

I must ask - what’s the mindset behind this text?

How deep in the rabbit hole have you delved already?
I’m talking about different lubricants, toys, temperatures, materials, locations, amount of people at the same time, kinks, smut/porn, angles, positions, pressure, length (in time) etc.

Probably trying sex with two women in a threesome.
Maybe having a relationship and a FWB at the same time.
