Kissing can be fun and adventurous, whether or not it reminds you of a chicken carbonara sub.
Knowing will make it much more likely that a girl will make the first move.

Ready to extend the kiss into a longer makeout session? Slowly build the amount of tongue that you use and focus on playing with her tongue.
