Well, My girlfriend of about a year has decided that I am not good enough in bed and wants to see other guys while still dating me. She is 25 and I am 28 . My penis erect is around 5 inches or so and I honestly try but cant satisfy her while having sex. We do have oral and she get spleasure from that but she told me she needs more than that. I really love her and want her to be happy but am not sure about this lifestyle. Should I stay with her? Maybe I can do something to make it better? Has anyone ever experienced this sort of situation before?
