I had a brief encounter with a massage person 2 days ago where I had unprotected oral sex for a short period, less than 5min total. I've been reading throughout the site any exposure for all intense purposes are rare. I didn't notice anything unusual as far a lesions, bumbs, sores, bleeding etc. I've read on the forum some sti's aren't transmitted via oral sex, But which exactly are and what is the chance of exposure, specifically syphillis? I was mainly concerned with that and Gonorrhea. Maybe I'm deluding myself but am I missing anything before I do drive myself crazy.
Thank you in advance.
