How to prevent dry lips before a kiss due to nervousness help?

I have no kiss no boyfriend, it’s just in case I do kiss the boy I like. Which might not even come true LOL but I been getting nervous lately around him& my lips get super dry due to this. All day I put on chapstick but I’m so nervous my lips dry up and if we do kiss one day my lips will be fucking dry and it’ll be bad kiss 😭 I can’t in the moment whip out a chapstick and put it on no it’ll ruin the kiss LOL
