1. Don't let him play other roles
Do you know what role your FWB plays in your life? First of all, you need to find out what he means to you, so that you won’t do something that you shouldn't do. For a casual encounters, FWB is your friend plus sexual partner. First, from the perspective of friends, you should treat them the same way as you treat ordinary friends. You can have some normal communication, which can help you solve many problems to some extent. But deep spiritual communication is something you should avoid, because it will spark your love. Secondly, we start from the perspective of sexual partners. In front of a new partner, you should be sexy and bold. You should try to show your sexy side in front of him, which will enhance your sexual experience and make your relationship longer. Besides, you can try all kinds of new things boldly with him.
2. Envy is a poison
If you see your average friend walking with his girlfriend or hugging, do you feel angry or jealous? Of course not. People just care about people they like. So, if you're jealous of your FWB's behavior, you've already had a crush on her. This kind of situation should be avoided by all the adult affair finders. If this happens to you very unfortunately, you have only one choice, that is to be brave enough to tell your friend, even if you may end the relationship with him. Don't try to suppress or cover up your emotions, because it will cause resentment between you.
3. You are still friends
When you're in a relationship, you need to maintain your friendship while trying to play your role as a sexual partner. You can go to some friends' parties and activities together. But make sure you don't fall in love with each other during these contacts.
