I had 2 FWBs when I was 20. My (ex)BF of 2yrs had cheated and left me for a girl we worked with. There was almost no intimacy, despite my trying, because he was really just using me (free place to live,food,rides etc) until he could find someone he wanted. After going so long without it, I went wild. 2 FWBs, they knew about each other, they had their scheduled nights they'd come. This went on for about 7 months. It was great. It ended because I moved across the country.
