Hello, doctors. I am a 23 year old male, and I slept with a girl 3days before, during that night, we had shallow tongue kiss which lasted for 4 second, and I accepted her blowjob for 2 second, but still in a slight way, then she helped me to masturbated without washing her hands, because she took off her shoes and touched the cell phone and other staff before, I felt really panic about the behaviors mentioned above, so please help me to analysis the risk of infecting the STDs like the syphilis and others, thanks so much!
