This is routine.
Niu Nan is a very traditional and conservative boy. On weekdays, they always follow the rules and do things in a down-to-earth manner, and dare not do anything shocking. For cattle people, they are strictly educated by their tutors, so they are quite disgusted with some more open things. Emotionally, even if Niu Nan meets a girl she likes, she will keep a low profile and won't make intimate moves. So when it comes to sex, Niu Nan is also very conservative, afraid to indulge in debauchery, but it seems a bit routine.
You are dispensable.
Niu Nan's sexual needs are relatively small. Even if they don't have sex, it doesn't matter much. They can live a good life. This is because Niu Nan spends his time and energy on other things, such as studying how to make more money every day. Therefore, Niu Nan has no mind to think about sex. Even if there is a woman's active temptation, Niu Nan is in hindsight. She doesn't think about it at all, so she often gets angry with girls.
Can't bring pleasure to each other.
Niu Nan actually has conservative ideas. They always think that a man's mind should be in his career, not too much love and affection. Therefore, Niu Nan is completely isolated from romance. Although he is a down-to-earth boy who won't mess around, he actually lacks interest, let alone sending flowers on Valentine's Day and packages on Memorial Day. In bed, cows are also easy to deal with. I don't consider each other's feelings at all, and I don't want them to have a pleasant experience.
Summary: For the men of the zodiac, their greatest performance in bed is good performance. For them, sexual demand is relatively small, and it can even be a dispensable thing. For men who belong to cattle, it is a bit like a routine in bed, and they don't know how to have fun.
