Touch ID sweaty hands

When I first got my iPhone 8 what made a great impression to me was that the Touch ID was so good even when my fingers were sweaty which is almost always lol. Anyways, yesterday my friend's hand was a little wet and wanted to move my phone from the bedside table to my bed and when he grabbed it a little moisture went on the button. I immediately wiped it off and ever since then i feel like my button is malfunctioning.

It still works whenever my hands are dry but when my hands are sweaty the performance, I feel like, is significantly worse. My friend thinks I am paranoid and that water cannot affect it for 2 seconds + the fact that it's a water resistant phone.

Any advice? Because when my hands are completely dry it works fine but I don't know
