I'm from a neighbouring country, not Ukraine itself! I do happen to know (formerly) married couples of Ukrainian women and Westerners.
I don't have anything more to say in general than what I already said.
Some random thoughts:
If you want to have sex, go and have sex, that's going to be really easy in Eastern Europe. Like if I think you're fuckable (hot, cute, whatever you want to call it), we have a few drinks, make out, have a few more drinks, have sex, end of. If not, I just pass you on to my friend who thinks you're hot.
I have met many foreigners, though, who act interested, but then they never really want to make out? But they would keep talking to me. That never happens with locals, if they don't want to make out, local guys don't keep an exclusive conversation going. And I never really know if it's a culture thing or if they're just too shy to move on to talking with someone else who they think is more attractive than me, or they are gay, or they just like to talk with me that much. So I find a lot of Westerners bothersome, don't keep talking to me if you're not that interested. If they were great at conversations, I wouldn't mind talking for days or weeks, but I've mostly met boring Westerners so far. Shoutout to that Eastern American sounding buff guy who was in shorts and some sleeveless shirt in the middle of winter, now he was fucking weird, so we had good conversation, something rare with foreigners. I hope he got laid quick and didn't freeze to death.
