Circumcision is not too late, but it is best to do it before marriage. One is not to delay your partner's sex life, and the other is to have a certain adaptation period after finishing, that is, the friction between the glans penis and pants will reduce the sensitivity of the glans penis and prevent premature ejaculation. However, after marriage, because the foreskin is finished, direct sexual intercourse is needed, and the sensitivity of the glans penis increases after circumcision, just like a person taking off his clothes at once. It may cause premature ejaculation in a short time. Simply put, after circumcision, your sexual ability may not be as good as before in a short time, but if you think about it for a long time, it is better to cut it.
