Here's my general experience in the hobby:

-First experiences--legal brothels in Nevada (not quite the hobby per se, but P4P nevertheless): about 50% of the time it was simply OK to bad. Lower value (e.g., intensity and type of activities) for money paid.  30% was pretty good, only about 20% being excellent.  For that reason, I ventured 'out into the world' to sample the hobby ladies. Plus I got a bit less chicken-shit about LE, etc and more gutsy I suppose.

-For hobby providers, my experience overall is about 80% good to excellent, which includes enhanced activities such as kissing and bbbj.  That is a real contrast to the LPIN scene, where GFE means that they give you more eye contact, lol.

-About half of the good to excellent are about average on the second round with the same lady. Something about the second time that often doesn't play out as well as the first.  It's not just my expectations are changed (on the contrary, now I know what to expect), but sometimes the performance just seems a bit lackluster or something.  I haven't quite figured it out.

What's been your experience?

The more I see them, the better they get in all respects. And they nearly always start out excellent to start with.

Never done LBIN.  However I choose my friends carefully & only invest in potential Favorites.  I find that subsequent meetings are better but then if I did not click on the first meeting, there is no second.

and most of the time I'm a one and done kind of guy.

simply because there is so much good sex to be had out there from so many pretty ladies  - too much opportunity to be missed.

Repeating often does lead to disappointment at some point - perhaps sometimes it is expectations, sometimes being taken for granted.

I know a very very few, very special ladies who have shown a consistent and high level of appreciation for my repeat business, and I enjoy them very much.

Otherwise I am entirely an once n done guy.

I tend to repeat with the ladies I click with, so don't see a wide variety. Of course I stop repeating if the same level of excitement and service is no longer demonstrated on her part.

our genetics drive us to be a one-and-done guys. Our big heads calculate the risk factors and comfort levels etc. and deviate from our genetic code a bit, but not much... at least for Alpha males.

I remembered Lovegoddess said most of the hobbyists are alpha males.

before TER, and and after TER.

Before TER I'd say I had about 20% excellent, 50% good, 20% so-so and 10% awful.

After TER I'd say the breakdown is:  50% excellent, 40% good, 10% fair.

Guess which era I'm enjoying more.

Yes, independent ladies are a world apart from the Nevada brothel scene.  

However, I will disagree with your 2nd point.  I usually have a better time on the 2nd or 3rd visit than the first visit.  Might be something about being more comfortable with the lady or her with me.

I have never done the LBIN thing either. I do my research and about 80% of the time it has been a good or great encounter. Of those, if I click with someone, I'll continue to see her. I have a couple I have seen multiple times and will continue to do so. The comfort factor is at play here, we know what the other likes. Those I haven't seen more than once, we didn't connect or are on opposite sides of the continent. The 20% that were not good encounters and for some strange reason, after I reviewed them, two of them pulled their files off TER! lol. And they had been around a LOOOOONG time, using pic probably 5-10 years old. (So I TOFFT'd them for some of you guys, and now they aren't around! lmao.)
