Let me ask you a question (assuming you are a man)
Would you like to be called a boy?
Imagine being addressed like this (in a group of 90% women)
"Hello ladies and boys"
Wouldn't that feel insulting? And weird?

guys and girls - OK. Very casual.
ladies and gentlemen - OK. Somewhat more formal.
men and women - Weird. Sounds stilted.
boys and girls - OK, depending on tone. Would work better with an ironic tone when addressed to adults. Would sound stupid if expressed in kindergarten teacher tone.
ladies and boys - seems a bit forced. Also, it makes me think of "ladyboys" (e.g. transgendered Thai prostitutes)
