1. You think sex is based on stable feelings
Many people feel that they can only have sex with another person after they have fully trusted him and have decided to spend the rest of their lives with him. This is a traditional and conservative idea. I'm not saying it's wrong, because everyone has their own independent thoughts. But what I want to say is that if you have this idea, there is no doubt that this casual NSA relationship is really not for you. The FWB relationship is set up specifically for sex, and the relationship is forbidden. Let's not talk about whether your personality is suitable for this relationship. Your idea is already against the idea of this relationship. If you want to maintain a positive quick flirt relationship, you need to actively explore sex with your friends and find satisfaction in the process.
2. Sex plays a secondary role in a relationship.
For serious dating pursuers, sex plays a secondary role in a dating relationship. Goals, responsibilities, and a shared future all seem more important than sex. But for NSA relationships, the opposite is true. You don't have to be responsible for each other; you don't have to talk about your goals; you don't have a common future. In this casual relationship, sex, and only sex, is dominant. If your idea is exactly the same as the former, you'd better not involve in this type of relationship, because this relationship is not suitable for you, it will make you feel very painful.
3.You feel like you're being taken advantage of
First of all, try to think about how you felt last time you slept with a man. Do you feel satisfied and then forget about it, or do you feel that you are being used by this man and feel uncomfortable? If you are the former, Congratulations, the door to NSA relations is open to you. But if you are the latter, you'd better stay away from the relationship. Your mind has decided that you are not suitable for this relationship.
