i was just wondering about oral std's or sti's, i found little to no information about them online, i mostly find vaginal or penis std's. and i think this is equally important.

after oral sex, how do these start? can you get tested after less than 5 days of having unprotected oral sex? what are some of the first symptoms? if you have oral sex with a guy or a woman, which one is easier to catch? can you get it only if you were giving it to them but it lasted very little, maybe from a few seconds to less than 5 minutes? and can your mind play tricks on you and make you feel like you have it, but you really don't, because you are stressing about it?

thanks in advance for anyone who answers.
