If you want to maintain this FWB relationship without changing your friendship, you should follow these suggestions.
Full respect is necessary
Yes, in any relationship, mutual respect is necessary. It's a social rule. Of course, FWB relationship is no exception. Many friends will respect each other in the process of getting along, but when sex is involved, their friendship will be affected to a certain extent, and their attitude will also change. Although casual sex is at the center of a NSA relationship, it doesn't mean you can treat your friends in a casual way. Since mutual respect is necessary in friendship, respect will play a greater role in this more sensitive sexual relationship.
Don't limit your choices
Never be bound by a NSA dating relationship. You are not in a committed dating relationship, and loyalty to your partner is not necessary in that relationship. Instead, it puts you in a passive state. You're more likely to fall in love with your partner when you give up other options and focus all your attention on him. Most importantly, when a serious dating relationship is not what your partner wants, your over focus can make him feel stressed and even want to escape the relationship. This is not only bad for the development of your relationship, but also makes you feel pain. So keep your choices open. When you use more choices, you are less likely to fall in love with your partner.
Tell your partner the truth
In fact, it's hard to be completely honest with another person in a relationship because the truest thoughts in our hearts may be cruel truth to others. So, very few people will tell the truth to another person. The same is true of NSA relationships. But sometimes lies can make things worse. Even white lies can have a lot of side effects on your relationship. But if you don't want your partner to be hurt more, you have to be honest when necessary. When you want to give up the relationship, when you have a new choice, you have to tell your FWB frankly.
