on 13th of March. I met a sex worker and recieved an unprotected blowjob for the first time in my life. Since then I am feeling mild pain in stomach area. 12 days after the exposure I did the urine pcr for Clamydia and Gonorrhea, They came back negative. Blood tests for HIV and syphilis came back negative. two days ago, i found 3 small bumps on my scortum and it disappeaered withing 6 hours of time. Today in the morning I observed same bumps, but this time all over the right side of the scortum. When I was checking in the evening, those bumps have disappeared. The colour of them are same as my skin colour.
Please help me.
I am so nervous. scared.
1. What are the possible std s I can have ?
2. How should I change my life style accordingly ?
