When I'm with a girl, I become erect very easily, and usually stay erect for awhile. However, once the girl takes out my penis I don't stay erect long at all (maybe a minute tops) and I do not ejaculate. A lot of times my penis goes soft and then a couple minutes later it will become hard again, then the girl starts playing with my penis and then it will go soft again
Anyone have any advice on how to solve this problem?
