I don't know if any other guy has experience this but my last g/f was obsessed with cock (I first thought
it was just mine). She could not stop fondling it and manipulating it, or sucking and licking it. I recall waking up a number of time with her soundly giving me head. She swallowed and drained me often.

Then, one day, she "vanished" and I heard she was "with" another dude, known to me. From school gym I knew he was not bigger than me. I never understood where I went wrong. Perhaps I never will. Women seem to be a mystery to me. I do miss her attention to my Oscar. He does, too.
