Update: Negative for syphilis at three weeks. I still have two circular painless lesions on the sides of my tongue, but they havent really turned into chancres (from photos and descriptions on the net). Not out of the woods yet as I will retest at 6 weeks. I hate waiting, it's the hardest part. Also cannot find a discrete place to get a throat swab for chlamydia and gonorrhea.
Hi getting any std from giving a female oral sex is as about low risk as possible as the bigger risk is when a person gives a penis oral also not std show symptoms the next day.
Test for syphilis and herpes only if you have a long term partner or if you develop lip sores about 2 weeks later.
