If you feel itchy scrotum after having sex with your partner, it is usually very likely to be caused by fungal or bacterial infections, and it is also very likely to be caused by the lack of personal attention to sexual hygiene or the failure of your partner to clean your private parts adequately before having sex. For this symptom, you can first wash it with warm water, and then your underwear should be changed frequently. The actual fact is that you can find a lot of people who have been in the business for a long time, and it’s a good idea to go to the hospital for a checkup, as it could be a scrotal fungal infection or scrotal eczema.
