Titggling is one of the most enjoyable things any couple can do. It brings you two very close, and tells you a great deal about the relationship(Plus hey, you get to snuggle with your girlfriend's tits!). Bad Titggling can ruin a relationship.
First and foremost, you have to try to be a good Titggler. It should come naturally to you. If you've ever been held by a crying hooker, or anyone for that matter, you should have the basic idea how to titggle.
