Before you stuff your bag with goodies, decide how big it should be. HOOK recommends hiker’s waist packs because they’re not-too-big-not-too-small size makes an easy grab-and-run. Small duffel bags are cool, too. And always keep it within eyesight.

Clients may “forget” to have them handy so keep some with you. You won’t need a big bottle of lube (use a silicon lube ‘cause it doesn’t dry out quickly!) and wrap the bottle in the gloves to avoid a mess.
 

At least have enough for cab fare or a subway ride plus a telephone call in case of an emergency.
 

This a little tricky as you won’t want it in the wrong hands, but if you run into any trouble, it will come in handy.
 

Not as dangerous as knives or guns, use it to defend yourself and RUN!
 

A rolled up t-shirt and pair of shorts will be an ass-saver when you suddenly find yourself nearly naked, running out the door. Plus, it will definitely help you feel a little more fresh between clients.
 

Granola bar, raisins, trail mix, etc. are good in case you don’t have much time between clients to pick up a bite. They will help keep you energized without feeling heavy.
 

Nasty breath just isn’t sexy. After dinner with a client or whatever, you won’t want to brush your teeth if you’re going to do any oral later. Again, just keep a travel-size bottle with you.
