Hi, Two weeks ago I have been to massage parlor, the lady massaged my back with oil and gave handjob at the end of massage. I was very freaked out due to any STDs I might get infected by this incident. As soon as I got home I washed my penis with hydrogen peroxide and soapy water. 4 days after this, I developed penis head dry and chapping, and two tender sores. I visited my doctor and he ordered HIV gen 4 due test and other STD tests. Also doctor told me that the sores present are balanitis and developed due to soap or hydrogen peroxide. The blood was taken on 7th day after this incident. All my tests came out negative. My questions are 1. Is it possible to get HIV from handjob? 2. What are chances duo test might detect anti gen at week period after incident 3. Should I repeat HIV test at 28 days or 3 months? 4. Does balanitis makes me prone to infection? I never had unprotected sexual encounter beside this ever in my life. Please help, I am freaking out by possibility of contracting HIV.
