A while ago, (a few months, maybe), I hooked up with a guy who said he was tested for all STDs and came out clean (we're both in college). He masturbated, and before ejaculating, he fingered me. I got tested for chlamydia and gonorrhea about 5 days later and came out negative, but I just found out that the incubation period is longer than I thought. Could I have caught it from this?
In theory, it might be possible to transmit chlamydia (and gonorrhea, for that matter) by hand-genital contact. But if it happens at all, it is exceedinlgy rare. For the purpose of STD risk, only vaginal, anal, or oral intercourse counts. Kissing, mutual masturbation, body rubbing, etc are not significant risks.
Anyway, you are confusing incubation period with the interval for accurate testing; they are not the same. Incubation period is the gap between catching an infection to onset of symptoms, which is typically 2-10 days for gonorrhea and 7-21 days for chlamydia. However, for both infections, testing probably is accurate within a couple days of exposure. Your negative tests are reliable evidence you weren't infected.
