So like Herbt, I recently overhauled my rotation:
Now have two frisky 19 yo, one who thinks anal is just another position, a super sensitive (touch her anywhere and she orgasms)  22 yo and my 'unicorn,' a 32 yo eastern European lady with a body to die for!
So I'm planning on visiting my unicorn for a month or so shortly, but am a little concerned whether my rotation might drift away while I'm banging away in the EU - especially since they are all are so new, young and very submissive.
A question for you guys that travel alot: how do you keep the babes from being oversampled by the hordes while your traveling?  I mean, I guess I could pay something to keep them interested, but of course, there's no guarantee they won't just take the money and run.
Suggestions, or experiences?

I would never recommend you start a framework of paying them NOT to be with you. That just reinforces the walking ATM image we all avoid.    
.
The reality you need to accept: What makes you think they are not banging 3 other guys a day when you are not with them now? And what makes you think they would stop (or slow down) while you are away?  Why do you even care?  
.
If you are really worried about being dropped from their rotation - and yes they each have a rotation of SD's -  then here's a suggestion: Assuming you have a BF-ish relationship with each of them, make time to stay connected through email, text, facetime, etc., and maybe, just maybe send them a small present (flowers?) about a third of the time into your trip to keep you top of mind while on travel. Let them know you "miss her" and "wish she was here" and "I have to bring you here soon - the sunrise here reminds me of your eyes", blah, blah, blah bullshit any guy would tell his GF.  Remember 19 to 23 year old's still believe that their "guy is special because he's so into me!".  So milk it while you are away on your "must-go business trip" (to bang the shit out of that MILF Unicorn for a solid month).  
.
One more suggestion (having recently spent a month in Australia with my #1):  Schedule one day a week (or so) away form your Unicorn if you can. Even 24x7 pussy needs time to rinse off and air out after a while.  You two will get along better if you add some scheduled "me time" to the mix.  

It's so fucking close to the advice I would have given it makes my post almost irrelevant. lol

 
The only place I differ with you is that I can't imagine spending an entire month with any woman, I would need more breaks than once a week personally, but that's just me. I am a pig not a cat.

 
One additional note to PP. If you are actually going to Eastern Europe to visit your "unicorn" you really need to set more time than once a week to be away from her. The women in Eastern Europe are DDG and the hooker prices are a fraction of what you are used to here in the states. You may find yourself in a country full of "unicorns" Do you really want to go to an "all you can eat buffet" and eat nothing but the crab legs with out at least trying the roast beef or the baked salmon? lol

LOL!

Truly we must be brother's from another mother.  Which makes me wonder who the fuck my father was whoring around with....

(Ok I know the correct grammar should be "...with whom my father was whoring around..." But it's funnier the way I wrote it, so fuck off all you grammar cops.) :p  

I'll echo your note on taking advantage of the local flora and fauna.  Take a side trip to a nearby city for a "business meeting."  She doesn't need to know it's really a "side" trip for a piece on the side.

Fuk!
I think I've been on SA too long...starting to think that most of the girls are basically semi-pros and that the only thing that motivates them is money.

Treating them like gf's for a month is not only going to make them happy, but save me a crap load of money.  Flowers....yes flowers!  There's no girl in the planet that doesn't like flowers   lol

Thanks again dudes!

Oh, btw, already put this advice to use an hour ago, changed out a dead battery (less than $100) for one of the 19 yo and got an amazing bbbjcim as a reward as I was about to leave!

Life is really good!

For what it's worth I'll add my 3 cents. I'm currently in Japan for a 2 month trip alone. My SB back home texts me "I miss you" once in a while but I have no delusions. She's making the ends meet somehow.   When I was a newbie and had another SB and would leave for 1-2 months I would send her 50% of her normal intake from me.  Big Mistake.  When I got back she had turned from a SGF into a little hooker and I soon dumped her.

The down side of this trip is that the little hottie Japanese and Chinese girls are asking 500 ppm and won't budge. The foreign girls are 300-400 but that's not what I want!

and as Herb and Gambler have said, I stayed in touch with my two local favorites, sending pictures of my travels, little texts about how I miss them and can't wait to see them when I get back, etc.  So yesterday my reunion with my hot 19yo was amazing, and I'm be visiting the other very soon.

What's odd for me is that shortly before taking this trip I experienced an unexpected attrition rate.  Several SBs ghosted or simply moved on to greener pastures.  So I had fewer SBs left behind to worry about, and am rebuilding the rotation as we speak.  Such is life in the bowl!

Well my current rotation has temporarily expanded to eight which I don't think is sustainable anyway.
Had six different hotties the past week, and think my health can't take hits like that much longer    The average age is 22 and they have boundless sexual energy!

And, as a reflective moment for me, was just away for two days and I really appreciated the ladies who asked how I was doing, sent a couple of nudies, and seemed to take an interest in what I was involved in.

Think I might take the advice offered, but at the same time just let attrition cull part of the rotation, and maybe even focus on the ones who seem more genuinely concerned as to my well being outside whether I can PayPal over some funds to cover a broken nail   LOL

But, yes...life is very, very good in the bowl!
