Do you use tongue in your first kiss?

it depends...if you want a deep passionate kiss then yes you should but if you are not sure about they guy/girl then for your first kiss give them a quick peck on the lips.
NOOOOOO!!!! The first kiss should be somewhat of a peck. No tongue. The tongue is like wasabi. It's good but it needs to be administered in small doses and definitely not if this is your first kiss.
