Warming and tingling formulas heighten sensitivity wherever you apply them — clitoral serums, G-spot gels, nipple balms, and options formulated for penis owners too. Warming lubes use heat-activating ingredients like capsaicin; tingling formulas typically use menthol or peppermint. Apply a small amount and wait one to three minutes for full effect. Water-based formulas are safest with condoms and toys; oil- and silicone-based options have specific compatibility limits — check the label. Patch-test first if you have sensitive skin.
