How does wetness affect the resistance of your body?

It reduces it dramatically.
Explanation:
Your skin is encrusted with salts as a result of perspiration (no personal comment, mine is too) but as it is dry it doesn’t provide a very good conductive path (the ions are not mobile.) A typical value might be several M
Once wet, the salts (mainly NaCl) dissolve, dissociate and can move. As a result the resistance may fall to a few tens of Ohms.
This explains why, in many countries, electrical sockets are not present in bathrooms with the possible exception of shaver sockets.
