I am 21 years old and my as****e ring is swollen externally. I have also managed to see white discharge of fluid from anus which is smelling awful, but there is no blood. When i wash my as****e and area around it, i feel better for an hour or 2. But again the severe paining problem starts after 2 hours. Pain i feel like very sharp. i am now living in a small village and i am quite sure that this is not any kind of STD. I also did nothing like anal pleasure etc. plz help me.
