I lived adjacent to your faithless country for several years. I know exactly which country you are speaking of.And there´s one thing I want to add, based on my experiences. I don´t want to discuss casual sex, since it´s forbidden on this forum, but I will use it as an argument for this topic.
To my friends, I always used to say - if you want to have the highest chance to get laid, date foreign girls (to be honest, going out with foreign girl from Tinder used to be almost instant ONS for me). I live in faithless country, where the most of the people are atheists and there are incredibly low moral standarts. And I came to conclusion, that environment is what make girls bad, not their background. Girls living in traditional societies are not that spoiled, because society punish them for their bad behaviour. And once they get into environment, where there´s no punishment for whatever they do, they lose their inhibitions.
I have met girls even from much more traditional countries, from very religiously strict backgrounds and once they got into liberal envionment like this, they became different persons. Back their in their home countries somewhere in xxx-stan, their families (and especially their alpha male fathers) think, that they are still virgins. But here, you can do whatever you want to them, as long as their daddy won´t find out.
Why there are so many onlyfans girls now? Because society don´t punish them and label them as a prostitutes, even though they are.
It has been stressed out in this thread for many times - girls just FOLLOW. And they also follow what their environment demands. Generally, it´s not woman´s moral, but society moral, what leads them.
You have to be extremely strong authority to make girl follow you and (or) God without slipping to society low standarts. Or you can start a family in muslim country, where bad behaviour is still punished.
A couple of thoughts. Even in faithless Western countries in agnostic Europe I found eligible trad type women if you knew where to look. Obviously Im going to focus on Catholic type girls since that is my faith.
Major Catholic shrines seem to fill pretty well on their masses.
TLM Churches do well and have a younger population.
Immigrant Churches (like Spanish Mass) are younger than trad churches, noticed some single women there.
Catholic Match is a fairly decent place to look, but you have a number of reformed (and not so reformed) women that have baggage.
Mainstream Novus Ordo Catholic churches in Germany, France and Belgium are probably not places you want to look. The average age is close to 70. There are a handful of single women you see every once in a while, but they are likely to have Globohomo beliefs that trump their religious ones.
