Oh that really is a homebrew!
Some will find chilli more likely to react to I think so before you make a whole pot full try a premix, but if that all goes well this is a nice idea. I prefer menthol to chilli myself, but the point where they both reach is capsaicin cream which is the essence of what makes chillis hot, but also has the cooling sensation of menthol, before it sets your body on fire.
Now rub it on your clit, Rach
It’s crazy strong, and will fuck you up. Use well diluted, or regret it.
