Hello, 5 weeks ago a man cum in my mouth (not my intention). It wasn't a blowjob, i thought he is not yet near to cum so i tried giving him blowjob but a soon as i placed my mouth near his penis, he suddenly cum making his cum (the 1st shot only) go to my mouth (under my tongue specifically). After 10 sec. I washed my mouth without brushing or gargle. Am i infected with any STD? I know you answered this kind of question millions of times but im really worried about this incident. I'm virgin and only did oral sex to 4 men my entire life (im 24yrs old). All of which was not more than 10 sec because i don't enjoy it. Thanks in advance answering my concern. Thank you so much.
