I wonder what are the chances to have gardnerella vaginalis by having oral sex without using condoms. I hate using condoms during oral sex, and what about my partner? There are no condoms for vaginas! Me and my partner don t want to quit the oral sex habit that we both practice and enjoy doing, just for the fear of this medical disease. I should mention that we once had it and we both had medical treatment. Our doctor said that we should avoid getting the vagina into contact with oral fluids so that we can protect ourselves. Any suggestions?
