you should see what happens when a young, mid-20s and really good looking American guy shows up in Ukraine
all the women start circling him like sharks and snarl and hiss at all the other girls
youth is wasted on the young
I would loved to be that guy lol. However I know I am not really good looking unfortunately.
To be honest I am probably lucky to have one girl and one who is into me at least it seems to me she is.
The main time I might have gotten anywhere close to the scenario you mentioned Krim is in Copenhagen. There most girls are blonde so me as a 6ft tall brunette guy got some attention, not like the scenario you mentioned not that extreme but a good number of looks and even feeling in some quiet museum locker room that I might be raped by a group of them lol.
Decades ago Copenhagen was probably even more blonde than it is now with fewer visitors. If I had been a pretty boy instead of an everyday dude they probably would have raped me I had the feeling that they were teetering on the edge of it

Main problem with Denmark though is that it's an EU country, so Gender Equality (Equal Pay) and no issues to effect the availability of Men to Women so in reality getting a girl would potentially be hard even if a foreign guy with brown hair. Their interest probably just curiosity maybe intense curiousity but probably nothing more. Again the modern society values come into play and workplace situation like any Western Society I guess.
I wonder other than looks what's the tipping point that would get many Ukrainian girl interested in a Western guy 🤔
