I apologize if this has already been answered somewhere, but I couldn't find it.
When there is a series of items or events in a sentence and they are connected by ands, do you need to insert a comma before each of the ands?
E.g. He went biking and sleighing and skating.
Additionally, what if the words are connected by or?
E.g. second or third or fourth.
Since any answer that addresses the correct use of commas will likely be somewhat opinion-based, it is difficult to answer your question; however, I suggest that you purchase either the Chicago Manual of Style or the Gregg Reference Manual, and read their respective sections on the use of commas. For instance, both agree that a comma is required to set off a name in direct address; e. g., "Thank you, Jim."
As for your two examples, I agree with you that no commas are needed.
