In my opinion, the reasons for choosing a quick flirt relationship are as follows. First of all, many people don't want a stable dating relationship, but they want a sexual relationship. Second, people think that this casual sexual relationship should be simpler, because there is no emotional thing involved here, including commitment and responsibility. Third, it's exciting to have sex with different people. Causal enumerators can end a FWB relationship at any time and establish a new relationship with new people. But traditional dating doesn't do that.
Whether you have sex with your friends on purpose or fall into such a relationship unintentionally, it is a very difficult thing to transform friendship into sexual relationship. The best way to handle a relationship properly is to find out what kind of relationship you two are in and how you want to maintain a good NSA relationship.
First of all, you should make sure that your ideas are always the same. That is to say, when you decide to develop an FWB relationship with a friend of yours, you need to confirm in advance that he has the same idea as you. Remember, never develop such a relationship with someone you really like, because as time goes on, you will have more emotional dependence on him. This is what adult friend finders should try to avoid in an NSA relationship. So before you start a FWB relationship, ask them what they think.
The second is setting boundaries. Many people in FWB relationships don't know how to draw boundaries and what kind of boundaries should be drawn. Setting boundaries means that you need to have enough communication before the relationship starts. You need to tell each other what you really think and need. That is to say, you should expose part of your privacy to each other. It's an embarrassing thing for some people, and they don't want to do it. But what you need to know is that setting boundaries is the key to a positive NSA relationship.
The third is not to be too intimate. You are friends, and you are partners. Sex can greatly increase your emotional connection. But as long as you are able to maintain a casual attitude and avoid excessive intimacy in this relationship, your relationship will go smoothly.
