Hello. i am 17 year old boy.but my sex timing is just 1 minute. i noticed it when i masturbated.what should i do?

Here are some ...: The timing of ejaculation widely varies among men and most men ejaculate within 3-5 minutes of vaginal penetration, which is similar to manual movement for masturbation. You ejaculate in 1 minute (faster than what you like to), that is, "premature" ejaculation (PE). What you can do is practice self-control by slowing down the pace and length of strokes. More? Seek professional counseling.
