Does culture play in part of peoples reaction to love?

Yes, very much so! Your culture is what you are use too and what you have been raised in! Most people find it hard to differ from what they are use too! For example if it is wrong to hold a woman's hand due to cultural beliefs then the man will not hold said woman's hand. You have people who stray from their culture for varied reasons and these people are going to be more open minded and willing to understand or accept the differences between their culture and others. It does take time to "reprogram" someone's thinking and behavior when this is all they know.
