Patient's question:
Here's the translation of your text into English, with the line breaks preserved as instructed and all other Chinese text translated:---
Below, when it's not hard, I can pull it open by myself. If it's hard, I can only expose less than half of it. What's wrong with this? Also, I usually masturbate once a day. Will I get sick? When it's not hard and I pull it open, there's a sensation on the head of my penis as if it's covered with a layer of skin. What is this? I'm asking for expert help.

Doctor's answer:
Hello, when the penis is flaccid, the glans cannot naturally protrude, but it can be exposed by hand, which is classified as phimosis. When the penis is flaccid, the glans cannot naturally protrude, but it cannot be exposed by hand, which is classified as paraphimosis. Both phimosis and excessive prepuce can have significant harmful effects on the health of both men and women. It is recommended to seek treatment at a regular hospital as soon as possible.For men, the glans is kept covered by the prepuce for a long time, making it overly sensitive to external stimuli, which can lead to premature ejaculation. Moreover, excessive prepuce is prone to infection and the accumulation of smegma. If hygiene is not maintained, chronic irritation can cause chronic inflammation of the glans and corona of the penis, and in severe cases, it can lead to penile cancer.
For women, if a husband has excessive prepuce, smegma can enter the female reproductive tract during intercourse, causing gynecological diseases. Chronic irritation of the cervix due to multiple long-term chronic stimuli can lead to cervical cancer.
