First of all, we need to confirm whether it is really circumcision, I have contacted many men who think they are circumcised and insist on having surgery, but the pre-operative examination shows that they are not circumcised at all. Circumcision is a condition in which the foreskin can be turned up in a soft state, but the glans cannot be exposed at all. As long as you can still see the glans, it is not circumcised. When urinating, urine can be discharged directly without passing through the foreskin cavity, even if the urethral opening can be seen, it should not be considered circumcised. Unless the foreskin is very long and seriously affects personal hygiene and sexual life, circumcision is generally not recommended. The inner plate of the foreskin (i.e., the moist side of the inner side) has many glands that secrete and play a role in lubrication during future sexual life. If too much is removed, the secretory effect will be reduced and the woman will be uncomfortable during sex, reducing the quality of sexual life. Australian scientists have conducted a survey on sex workers, more than 70% of female sex workers think that the uncircumcised penis will be more comfortable. There is also a kind of obese patients, the penis is covered by the subcutaneous fat layer of the pubic bone area, will also be mistaken for the foreskin is too long, once removed, sex when the foreskin is too short, will cause men painful intercourse. In fact, this is called occult penis. The fat of the lower part of the penis can be removed so that the penis can be exposed normally. The circumcision is the narrowing of the foreskin mouth, the foreskin can not be turned up, whether in weak or erect glans can not be exposed, it is necessary to operate. Therefore, the general circumcision slightly long easily do not operate.
