I feel late to the party, as I see that this discussion has taken several turns, but I had some opinions about the original post, so I figured it didn't hurt to speak up.
I assume that a lot of men consume providers in the same way that I consume porn. I might go into the ballgame thinking that I want to get off to "sensual solo play" or "erotic couples anal" and wind up getting off to two army dudes attempting to fuck a blow-up doll while their older superior talks dirty about it. Go in looking for "sensual ATM" and wind up at MILFy stepmom walking in on her teen step-daughter blowing steady before she decides to teach her how to do it properly. Desires cover a large range and it's always a crap-shoot as far as what I both seek and wind up blowing my load over...so I understand how that would reflect hobby activity.
THAT being said, there's also a variety of hobbying styles. Some men know that they will see x providers this month to cover x needs. But they might find a trampy civvie gal or might get busy with work or their wives might start putting out. Other guys hobby like it's a science or a true hobby. You'll see organized to-do lists, both activities and ladies, and scheduled play times each month regardless of if the date is set or not. Some are on a search for the next ATF, or ForNowTimeFavorite. Hell, I've had guys who have tried to book me over the past 7 years but who have always pulled away when I'm in town.
And on a side note...I do find it weird to admit that when I provide I know that I'm considered a commodity of sorts to most of my clients. And really, I'd retire over such a realization if I weren't accepting of the fact that this happens in the real world just the same. If I'm gonna get off on blowing married dudes in suits while pulling a full time job, might as well make a full time job out of getting off on blowing married guys in suits. It's hardly a career move, but it works for me for the time being.
