Coronary groove is one of the sensitive parts of the penis, in the process of sexual intercourse, stimulation of the coronary groove can often quickly reach orgasm and ejaculation.
It is precisely because the groin is so important that it cannot be removed. The groin is an area where dirt tends to accumulate on a daily basis, so it should be cleaned to avoid accumulation of dirt in this area.
When there is discomfort or abnormal growths in the groin, it is important to seek medical attention.
