What is the Disorder –aliment called?
I got it I totally lose it and even have to finish with a hand job the second time I see a girl even if she is totally hot, the first time is very exciting

I don't know. I never get it. Sounds like you should never repeat. Just keep seeing somebody new.
I guess you can also never have a civvy relationship.

you are afflicted with spoiledbratitis..you are the brat that wanted a new toy every time your parents went to the toy store..you just could not stand playing with the old ones..

for 2 complete sessions.

My guess is you are married or have a SO, so you know the difference between a romp and a relationship.  I've tried to see providers multiple times and it is a rarity that I remain "interested" too.  Also, I completely get off on the "stranger sex" aspect of this, much more so, I've discovered, than trying to find a regular fuck buddy.  Keep getting that strange!

like it was the first time, so I decide there are better things to do than see her a third time.

That is on her, not me.

Are you sure that was not it?

I generally keep enjoying a good provider more and more, but I also space out the visits by several weeks or even months.

That's how I keep things fresh and fun.

I usually find the first several meetings each improve as we become more comfortable together...  PRESUPOSING that I want to see her after the first...

RH plays Cartman.

Mr. Spock put it eloquently - '... having is not so pleasing a thing after all as wanting ...'.  Before the first time - Want.  After the first time - 'Have had' , 'Have done' ...  

Not so much fun anymore.

i've found 3 girls that are dynamite, so i space my visits with them out and alternate...one month the blonde, next month the brunette, next month the older brunette, every so often someone new to shake things up...when i'm back to the blonde, it's been 4 months since i've seen her so she really gives me a good time...
