There are often friends on the internet who feel abnormal about themselves and consult if they have a sexually transmitted disease. In fact, the early symptoms of STDs can be manifested in many forms, when there is unclean sexual intercourse or extramarital sex, the symptoms of discomfort in the urethra, vagina or sexual contact site, we should pay great attention to. The first thing you need to do is to get a good idea of what you are getting into. It usually appears after an incubation period of 2 to 4 weeks after impure sexual intercourse. In men, it mostly occurs near the coronal groove, prepuce, foreskin, penis, and scrotum; in women, it mostly occurs on the labia majora, labia minora, or cervix. Due to the lack of obvious discomfort, the presence of hard chancre in female patients is often ignored until the appearance of the rash of stage II syphilis when they are seen in the hospital. In STD clinics, we also see stage I syphilis, or hard chancre, occurring on the lips of the mouth, tongue, around the anus, and nipples in women as a result of oral or anal sex or nipple sucking. Flat warts and palmoplantar rash are typical manifestations of stage II syphilis. Flat warts and the rash that occurs on the palms of the hands and feet and plantars do not cause discomfort to the patient, but they are very characteristic manifestations of second-stage syphilis. They all appear 7 to 10 weeks after extramarital sex or unclean sexual intercourse. During this period, blood tests can be taken to find out if you have contracted syphilis. 2, gonorrhea Pus flowing from the urethra and painful urination are likely to be infected with gonorrhea. Patients feel pain in the urethra when urinating, urinate more often, and cannot hold it in, all of which indicate gonorrhea infection. It usually appears 2 to 5 days after extramarital sex or unclean sexual intercourse. You should go to the hospital immediately. In addition to urethritis, women can also have cervicitis and vaginitis as the main manifestation. At this time, the symptoms of urethritis are not prominent, but mainly manifest as increased leucorrhea, which can be mistaken for general women’s diseases and delay treatment. If the vaginal discharge increases significantly after unclean sexual intercourse, especially if there is a purulent yellow discharge, you should go to the hospital for examination in time. 3, non-gonococcal urethritis discomfort when urinating, thin discharge from the urethra – early symptoms of non-gonococcal urethritis. The symptoms of non-gonococcal urethritis are not as obvious as those of gonorrhea, and patients mainly feel discomfort in the urinary tract when urinating, stinging or burning, and thin or yellowish discharge from the urethra. In some cases, gonorrhea occurs after an unclean sexual encounter, and the symptoms of non-gonococcal urethritis appear after medication for gonorrhea, because the incubation period of non-gonococcal urethritis is longer than that of gonorrhea, usually 1 to 3 weeks. Or, at the same time, no medication for non-gonococcal urethritis. 4, Condyloma acuminata Warts on the vulva indicate the possibility of contracting condyloma acuminata. There is nothing uncomfortable about being infected with condyloma acuminata, which neither causes painful urination, discomfort, nor ulcers in the vulva. It happens quietly and gradually increases in size until one day the patient notices, either intentionally or unintentionally, the appearance of small warts on the vulva. The incubation period of warts is long, usually 3 weeks to 8 months, with an average of 3 months. The actual fact is that you can find a lot of people who are not able to find out about this. The actual fact is that you should go to the hospital for a checkup once you have small warts on your vulva. 5, genital herpes Pay attention to the small blisters that appear in the pubic area. The characteristics of genital herpes are a small pile of about 4 to 5 small blisters in the vulva, with a burning or stinging sensation locally. These blisters quickly break down and become small erosions. The incubation period is 2 to 20 days, with an average of 6 days. The symptoms of genital herpes are mild and the vesicles can heal after about 7 to 10 days even without treatment. However, genital herpes is prone to recurrence and frequent episodes can occur once every 1 to 2 months, and it is highly contagious during the episodes, causing great psychological stress to the patient, so genital herpes should be treated promptly even though the symptoms are mild. In addition, ulcers on the vulva after unclean intercourse or extramarital sex can be seen in two other STDs in addition to the aforementioned hard chancre – an early manifestation of syphilis: one is soft chancre, which is often characterized by pus on the surface of the ulcer and is soft to the touch, but can feel obvious pain; the other is venereal lymphogranuloma The other is lymphogranuloma venereum, which is characterized by swollen lymph nodes that can often be felt at the root of the thighs along with ulcers on the vulva and are painful. The vulva can also open the door for other pathogens such as bacteria and viruses to invade the body, so the vulva ulcers should not be taken lightly and should be examined at the hospital in time to find out what is wrong and treated with medication in time. If the rash caused by taking certain drugs also appears to be a rupture of the genital skin mucosa, attention should be paid to the distinction, when there is often a clear history of drug use. Finally, it is important to remind everyone to stay away from bad behavior, cleanliness and self-love, and if you are infected with a sexually transmitted disease, be sure to check and treat both spouses together to prevent cross-contamination.
