I had this guy gave me a handjob over my pants. Like zipper on no clothes were taken off, I ejaculated but he didn’t directly touch it. I have syphilis and he knows but I got treatment about a month ago. Could I have reinfected myself?
Greetings.
No risk for syphilis or other STIs, since you had no direct skin-to-skin contact.
There is no such thing as syphilis auto-reinfection (that is, you cannot reinfect yourself).
If you were treated correctly, you no longer have syphilis.
