I have been circumcised before, and recently I found that squeezing the foreskin plate will give me the symptoms as shown in the picture, is this a normal growth or syphilis hard chancre.
Condition Analysis:
The result of your test is negative, that means you are not infected with syphilis, this is not a symptom of syphilis.Like you said it is just a hyperplasia.
Guidance:
Usually want to prevent STDs, pay attention to regulate their sexual behavior to achieve it, some other contact is simply impossible to infect.
