-label values- doesn't change the contents of a variable. Males still have 
value 1, but for some commands---tabulate, for example---you will see "male" 
displayed instead of 1. 

Don't  know exactelly what you want to achieve in the end. But you might 
either create a new string variable based on the "sex" using -decode-, or  
you might try 

. list var2 if sex=="male":lab_sex
