I have been married for only 7 months and I meet my wife weekly. After the first round, it takes a lot of time to get an erection for the second round and from few days my penis becomes completely erect in the second round but when I insert my penis into the vagina, after moving it in and out for a few seconds, my penis becomes completely loose without any discharge like it happens after discharge and after that I try for the third round, still the same problem comes & I discharged quickly in 1st round also.
