I don't know much about all STDs in general, but I know some stuff about HPV, and it can be transmitted in the way you describe. But almost everyone gets HPV at some point in their life, and most people's immune systems destroy the virus without ever getting any symptoms. Always get your 1 year pap smear, but other than that, you don't need to worry about HPV unless you do see symptoms like warts. As far the possibility of contracting any other STDs from the encounter, I'm as clueless as you.
oops sorry didn't realize you were a guy. you can ignore my little pap smear comment but the everything else still applies.
