There are several cultural specifics you should know about before communicating with Russian women. It is common for Russian people to be reserved. They are not as sociable as Americans. A lady you are dating might seem a bit restrained, but it is just because she has to know you better. On the whole, it is hard for Russian women to express their feelings. So you have to be patient and understanding.
By the way, ladies from Ukraine are a bit more sociable than Russian women. But a Ukrainian wife would be more inclined to argue about different things than a Russian wife. Women from Belarus have something in common with both Russians and Ukrainians. But always remember that every person is unique, and you will never tell what kind of person the lady is until you communicate openly and learn each other better.
Russian people are not accustomed to demonstrating feelings openly. Such signs of affection as kisses and hugs are supposed to be intimate.
It is considered ok to hold hands while having a promenade together. Dating courtship is welcome in the form of helping her in and out of the car, opening doors in front of the lady, paying for her bill in a restaurant or a café, etc.
Do not immediately proceed to the talk about sex with a Russian woman. Sexual relations are expected to develop naturally. It might be really embarrassing and abnormal for her to discuss sexual positions in thorough detail before “all of it” happened.
When you get married you will be able to openly discuss sex together, but at the dating stage of a relationship, a Russian woman aims at passion rather than its technical side. Demonstrate your passion for her without needless talks.
