Hi there. I read your query with interest. If all that you say is true, there appears a very slim chance of either of you developing any STD given you have been monogamous except for kissing you mentioned. The latter bit may transmit STD linked organisms eg. Herpes virus, Syphilis etc but extremely unlikely unless you have been with promiscuous individuals with known STD s at the time & had open or cut mucous membranes etc during those episodes of kissing et al. So assuming you are both being honest with each other & it does appear to be the case in your query & are practicing monogamy , this is the best case scenario as far as prevention of STD s goes. I don t think you need to speculate or worry any further. I do not think you need get tested for any STDs . Good Luck & do practice safe sex always. Dr Praveen Rodrigues MD
