If the foreskin is too long, the foreskin covers all the penis heads, and the foreskin mouth is not small, so you can barely turn it up to expose some penis heads. The foreskin is too long, so that sebaceous gland secretions in the foreskin cannot be discharged, and strange smelly scales are gradually formed. Skin scales are suitable for bacterial growth, so it will cause inflammation of the penis head and foreskin. Inflammation at the urethral orifice can lead to stricture of the urethral orifice after healing, resulting in dysuria. Penile cancer may also occur when the penis head is stimulated by echinococcosis for a long time. Usually, the glans mucosa is hidden under the foreskin, and the glans mucosa is usually less rubbed and stimulated, which makes the nerve sensation of the glans mucosa too sensitive. During sexual life, the glans penis is exposed after erection, and when the glans penis and vagina are rubbed and stimulated, premature ejaculation will be triggered because the glans mucosa nerve is too sensitive, leading to premature ejaculation.

I suggest you go to a professional hospital for examination and treatment, so as not to delay your illness.
