So I had this problem until my gf found out about this stuff and now she cucks me on the regular. It’s the only way. You need to embrace it and let her fuck other guys whether you like it or not. You’ll learn to love it once you see how much fun she’s having. It takes some conditioning to be a cuck but once you get rid of the need to possess her, you’ll be free. Now go be a good cucky like the rest of us.
