My fellow vets have highlighted the salient points. I can't add much more other than a few "Amens" as follows:
Yes, as you participate in this for awhile it can become a mundane experience. Like with all things, "it" can become routine, predictable, and un-fulfilling. Wait, are we talking about marriage?!?! LOL. Hence, when it becomes having sessions only because you can......pull back, take a break, save some money. Cause, during one period in my career I would have sessions for the sake of seeking that ultimate session....."wow, that session was so nice I know the next one will be even better!" Not necessarily so. After a period of this I was lighter in the wallet and realized I coulda got the same feeling from jerking off. Now, I may go a month or two with out scheduling a session. And there are periods where I will have a session at least twice a week; or I find that new ATF and we go on a sexual exploration for a period of time. I follow the ebbs and flows of my sexual cycle. And yes I have learned that I do have a sexual cycle. With that said, I do have those moments where I simply need to scratch that itch and schedule accordingly. IT seems like every time I have to work late and I'm leaving the office at midnight or later I get that itch and need a fuck and run session. Go Figure. But for the most part these type of fuck and run sessions are few and far between.
Now that I'm more experienced and in my 50's.....all and/or the majority of my sessions MUST have a level of connection and vibe during the time spent. If the provider is too detached, distant, etc then I don't book. I even ended a session once as it was clear during that 5 - 10 mins after you walk through the door that the session was going to be a simple fuck and run. The lady had zero personality and was all business. She didn't even try to act the part.
You may have read some of the previous threads regarding "Chemistry." Well that's where I'm at now in my hobby career.
You do want to be very aware to NOT let the hobby turn into a force of habit. When you do this you're just wasting money and opening yourself up to chasing the elusive higher high and end up falling off the cliff. And, if you have a SO doing it habitually will make you careless and exponentially increase your chances of getting busted. Even getting busted by LE as you will be less careful.
And I like the point one of the vets made regarding time spent. The hobby can be a time hog. Hell, to do this right and learn the ropes of the hobby properly can earn you a degree in P4P. In my early days the hunt for the right session and knocking on the incall door of a new provider for the first time was 70% of the rush and "feel good." Hell, the actual session was icing on the cake.
So yes grasshopper, take a break, given you're in your 30's see if you can scare up some civie pussy to your liking. That drama filled world and the many BSC ladies you'll come across will definitely reignite your passion for the hobby and its many fine providers.
