1.Do Latvian girls have sex with others before marriage randomly?
If they do,how many?
It's a private question, so I can't answer for *all* girls... But I suppose, that girls in Latvia act like all "our epoch" girls in the whole world. A girl should not be a virgin anymore before marriage, like it was in the middle ages. I am sure mostly all girls are being married after they have lost their virginity

Despite if you know the works of the
Latvian Man #1 Eduards Liedskalniņš, in one of his books he proposed that a "real man" should be married only with a virgin.
It's not about "random" sex, I am also sure most of girls take care of themselves and do not allow random sexual contacts too often, because it leads to ... you know what

Latvian girls are not "natural prostitutes" if we are about that. Finding a good partner rather always supposes swapping of few others, so it's a way of life. It's very rare nowadays when people are met once and married for the whole life

People became too educated for that, and wanting their life to be more perfect...
Some of them - yes

But definitely, not all. I would say, less than 30%.
I was smoking myself few years ago. Later I quit - because:
- cigarettes were getting more expensive (skipping smoking a pack per day would mean I am sitting at home instead of going to Bahamas each year)
- cigarettes became garbage, lost in quality, totally unhealthy and not comfortable to smoke at all.
As I know, many younger girls do not even start to smoke. However in Latvian schools, there is a big problem nowadays, because more than 50% of all pupils start to smoke being 13-14 years old (this also includes girls)...

3.Latvian girls don't like foreigners,Russian-Latvian girls don't mind it,is it true?
There are not a lot of purely "Russian" girls left to live in Latvia for now. Most of the "beauties" moved back to Russia, or To UK/Ireland/Germany/Italy/Swiss/France. If a girls speaks Russian freely, that would mean she just comes from a mixed family. "Core" Latvian girls start to lose their 'slavic' root and that's why in year, the image of them changed.

,I think I will submit my information about my property,my degree,my photos and so on on the Internet,when I'm 30 years old.I think it's also fine to senf information to girls directly.But not now.
I'm not even sure why would you need to do that at all

If you want to find a marriage partner, Internet dating is not about that. As I know, most of women/men which did find their partner over Internet, were split after short time.
To meet a good partner in your life, you must feel it, taste it, touch it. You can't do it online.
Good luck, and welcome to Latvia
