I met a young lady (21 years of age) a couple of nights ago and we had a sexual encounter that involved heavy kissing, mutual masturbation, unprotected oral (I received) and protected intercourse. Naturally I am concerned about having possibly been exposed to STDs. My question is first, what is the likely hood of me having been exposed to an STD (namely herpes, gonorrhea and chlamydia, crabs etc). Second, if I was indeed exposed to any sort of STD, when would I begin to notice symptoms, and finally how long should I wait to get a full test? Up until this point, I have only had one partner and we both were clean, I do not want to expose her to any possible infections. Thanks for any help.
