Do you guys have a little kit you keep with you to ensure you are prepared for a session?

Umm you forgot condoms....I always keep condoms/gum/deodorant/$500 in my all vehicles....and not just for the hobby. I do pretty well on the civvie side and nothing kills the mood like saying you gotta stop by 711 for rubbers

I hope all your vehicles are always parked in the shade!  Heat kills rubber condoms rather quickly.

a "hobby" for you if you go 3-4 years in a row without making any money.  It's a hobby for the guys, because like most hobbies, it's a non-deductible money pit that's hard to justify to other people who are not in it with you.  

Condoms are kept on my person at all times. I toss them if they've been in my pocket more than a week

to see a provider so I have no need for a "go bag."

Perfectly written
