In other words, 15.24 cm, so your erection time is 13 cm, which is normal. Don't worry too much. Some boys don't have an erection for a short time, but the time after erection will be longer than that without erection. My ex-boyfriend was only 3 or 4 centimeters when he didn't get an erection, and it was 12 centimeters after he got an erection. Now when my boyfriend is not erect, it is 6 cm, and after erection, it is 16 cm, so it is all human, don't worry!
