Why do lips chap?
If you keep your lips licked a lot, then they’re going to chap a bit more frequently, especially in windy weather. Boatman, you may have a sensitivity to the petrochemicals in her lipstick. Ask her to wipe her lipstick off before you kiss her. Also, if she uses the kind of lipstick that’s supposed to stay on all day, it might be that when her lipstick is exposed to air (as the part that’s on top of her lips and not next to her skin, it’s a very thin layer I’m talking about) it makes a chemical change to help it stay on and that may be abrasive or rough to YOUR lips and not to hers (because the thin, inner layer is touching her lips and not the air). There’s something about wintertime’s cold, windy weather that’s harsher on lips and skin than even summertime’s windy weather, though windy weather in generally will tend to chap skin and lips – because wind is drying to our skin and lips and winter’s cold is harsher than summer’s heat (lower humidity usually in winter).
