So i am 20years old and i had a circumcision surgery last year. I didnt have a girlfriend that time so around 1 month ago almost a year after my surgery i was with a girl and i finally had sex after my surgery. Before my surgery i could last atleast for 10 minutes minimum but now i barely last 3 minutes, even less sometimes. We even had sex 3-4 times a day and even at that time i felt i was cumming at the very beginning let's say around 30-40 second? Like realllyyy fast. I am feeling very bad about this so this is why i made an account on this site just to ask if anyone knows anything about this had an experience or anything and how to improve this?
Any response is helpful
