Ask the doctor to help me see what is the red dot on the glans? Like what symptoms? Suddenly there are many small red spots on the glans, which are neither painful nor itchy. There are also some penile parts under the glans, which are all in the picture.
The result you sent is mainly to see if you have a dirty sexual life history. If not, you should consider having something to do with glans. You can see a doctor in the local regular public hospital and register the dermatology department to let the doctor have a close look
According to the above description and pictures, if there is no itching, pain and increased secretion on the glans, it is considered to be caused by sexual contact or unclean living habits. However, this kind of rash formed by virus or bacterial invasion cannot be ruled out. You can wear pure cotton and wash the vulva and genitals frequently
