The reason for the sticky feeling in the underwear is that there are many reasons: 1. When the urine is stimulated after going to the toilet and not wiped in time, the underwear may feel wet and sticky. 2. If the vulva is not cleaned in time and the underwear is not cleaned in time, there may be a sticky feeling. 3. When the resistance decreases and the vaginal flora environment becomes dysfunctional and causes leucorrhea, the leucorrhea discharged at this time will be on the underwear and will also feel sticky. It will feel more wet and sticky. If this happens, if there is itching and even odor, it is recommended to go to the hospital to register with the gynecologist and have a routine laboratory test of the leukorrhea, to be treated, and to pay attention to personal hygiene. If there is no abnormal leucorrhea, no odor, itching, redness, you can wash your vulva with warm boiling water every day, and your underwear should be scalded with boiling water to disinfect and sterilize, and you can observe it for 3-5 days.
