Is there a remedy that increaes skin sensitivity? There is capsaicin and menthol wich affect the thermo and pain receptors and make it feel hot or cold. And there are vasolidators wich widen the blood vessels. But is there a chemical that increases generall sensation or libido. So that you could increase an erogenous zone or make one.

This pic is from a brony footfags fantasy dont judge because i actually wanna know if you can turn the footsole into an erogenous zone
