I think GR meant to say you received oral - not gonorrhea! Dont panic haha
Oral sex is pretty low risk for all STIs. Most healthcare professionals state that oral without symptoms does not usually warrant any testing. Statistically around 80% of males WILL show symptoms and like GR said, the bacteria live at the back of the throat so he would have needed to have "deep throat" you for a good amount of time. Even then it is not a massively high risk of infection due to other physiological factors.
Personally I would try not to worry about it and remember aunti jessies quote... Guilt does not equal risk.
Asymptomatic gonorrhea in males is pretty common. When someone does have symptoms, they normally show up in 2 to 5 days or up to 30. With females, symptoms usually develop within 10 days. However, you received oral. He'd have had a throat infection of gonorrhea to give that to you. When people talk about getting gonorrhea from oral, it is normally talking about someone GIVING it verses receiving it.
I had the dates of sex with my wife wrong, it was 4/24 and 5/18
