Naw but some people dont liek using rubber for oral.... [:)] How about if you or your partner doesnt sleep around, then you wont get an STD in the first place.
BTW dude, i did all about STDs in biology too, you can have an STD for a very long time without any symptoms showing up. Its more common on girls for this to happen, as its easier to see if somethings different oin your manpole [;)], but sometimes you may not notice, or sometimes it doesnt show up for a long time. I would get it checked out just to be 100% sure man.
