I'm sorry to say, but you can definitely get STD's orally. People can get throat infections that are gonhorrea, you can get genital herpes in your mouth (although you're MUCH MORE likely to get oral herpes genitally... the oral herpes virus likes to live both places while the genital herpes virus is more discriminating), and while I'm not 100% sure I'd bet you can get warts on your face from coming in contact with someone who has the human papilloma virus (HPV or genital warts)..... and most important to know, you can DEFINITELY get HIV from oral sex. While oral sex is "safer" than vaginal or anal sex it is not 100% safe. Grab some saran wrap and wrap that thing up before you go down! sexuality.org has a lot of good info on STD's (and other, more fun aspects of sexuality) I highly recommend it. Getting herpes made me become an "expert" on STD's - I only wish I had become one before... I probably wouldn't have gotten it! Still, my fingers are crossed that nothing is wrong with our original poster... it really could just be some sort of other infection. Please educate yourself now and keep yourself safe.
