Hello,
If you are sexually active, have multiple partners & go for unprotected sexual intercourse, it could be STI.
Get physically examined & get
STD tests done to stay on the safer side. If your tests are positive, you'll need a course of antibiotics & antivirals.
Avoid sex for a couple of days, avoid addictions of any kind for it may lower the efficacy of the medicines.
If you are not sexually active then take care of your hygiene. Wear soft, cotton clothes. Keep the genital area washed, clean & dry.
Take a course of oral anti-fungals. If the red streaks are itchy you can use
hydrocortisone ointment locally in the area affected. You can use any anti-fungal based cream also.
Hope I have answered your query. Let me know if I can assist you further.
Take care
Regards,
