Westerners and Easterners have different perceptions on how to deal with sex urges, particularly about having sexual intercourse before marriage. Westerners generally accept the culture of sex before marriage, in dating or even hook-ups. Even though some Easterners are OK with that, the discussions about this remains taboo and unacceptable. I am lucky to several time have some real discussions with several Westerners about this culture. When I was asked about why I should hold on, even without the absence of the desire to do so, I replied that I'm not allowed, the religion reason. However, I can still see the big question on their minds, moreover when they do not embrace the same principles that have been planted to the Easterners heads since we were just kids. When we have different roots, it's difficult to share the understandings. Recently, somehow I got the answers incidentally when I learned about humans behaviors, and I would like to share you about this. As a disclaimer, this article does not mean to judge your choices of life, some dimensions and circumstances work differently between people and I understand that.
