Hi, I went to a massage parlour and got a blowjob from the masseuse which i presume sexually active in her mid 30s. At first the blowjob lasted with a condom on all the way but she licked my testes too. Then I wanted to have a feel about what is the difference, so I took the condom off and she gave me oral sex without the condom for just a mere maybe 20 seconds or lesser before she gave me a hand job and I ejaculated. We did not have sex nor did I give her oral sex at all. So the only unprotected part I had was the mere 20 seconds. I know I made a mistake and I should have never took the condom off.
Can someone advise me on my risk level on STI/STD? As I read that some like herpes can get transferred by saliva? I’m not too sure.
Is transmission always 100% per contact if she has anything?
Thank you so much,
A Worried Male
