To clarify what vroom has said, change your lines so that where you are asking for input you have (for example):chomp ($usersex = <STDIN>);This will also prevent the output looking like this:

setantae
 is 23
 years old and lives in Wales
 In a year  will be 24 setantae
 is a boy
[download]

$userboy will still show up as nothing unless the user enters exactly boy or girl. You may also want to check for more common user input, such as b, g, Boy, BOY, etc.
