I am a male and recently (New Year's) received oral sex from what may be considered, an unclean partner. She probably only had her mouth on my penis for a maximum of 5 seconds but her mouth was on my testicles for probably 30 seconds. It pretty much just turned into a handjob after that (in which some of her saliva was used). I didn't ejaculate in her mouth. My question is what are the "odds" that I may have contracted an STD from her? And if it is possible, what should my main concerns be and how long should I wait to get tested? Thank you in advance.
