I wanted to give some of my experience while i was in Ukraine Kiev. Overall i would do it again even though i did have some bad experiences.
First off im 32 and average looking. so just a common guy i think.
I did a combination of three things before i went to kiev. I made 4 contacts using Elena models (phone numbers of talk to them over the phone), marriage agency, and 1 social.
Ok one thing ive learn is you will of course meet good and bad women in kiev. I meet more bad then good. I will explain. Now some of this just might be culture differences.
Since kiev is a large city pretty women will see a lot of foreign guys so dont think you will be some unique man if you travel to kiev.
Scamming to watch for:
Taxi money is the biggest scam i have found. For example a girl will tell you she wants taxi money to get to you and leave after the date. Normally she ask this at the end of your date. Ok now this isnt a big deal but a man who doesnt know the city could spend a lot of money on taxi. The common scam is she ask for more then it really takes or she takes the taxi to the nearest metro and keeps the rest of the money. yes this is 100% true. i actually made friends with a woman at the last part of my trip that admitted all this to me. We became good friends and then some by the end of the trip.
The second scam which is building on the first is they will setup 3 or so dates in one day. collection taxis but the dates will be close to each other.
The last is some agency's give the 'pretty' girls (not average) but the very pretty ones 1/2 of the money to the girl to meet a guy. The girl i was seeing told me this also. She had this setup. She admitted it helps pay the bills and etc. Our relationship didnt continue after i left because she need this income and wouldnt stop, but this is another story :).
Now are all agency's bad? of course not. are all women bad, no of course not also. But dont fool yourself on thinking you will pick up model type women easily. you need to ask yourself why she is going out with me.
Also i notice that if you get involved with a woman that doesnt speak english there is a lower chance you are being scammed.
overall what ive learn is what to look for in a russian/ukraine woman. it was tough to see what i want until i got there. i had fake illusions i had to work out. :)
i had woman that were very good and wanted to see me more but i didnt see them for a more pretty woman. had i did it over again i would stay with the woman that wanted to get to know me. This is very important, if you are looking for marriage and not a good time.
anyway i hope this helps if you travel to kiev. i know other parts of ukraine are different ;)
