I am on antibiotics now but he is not. We know that the incubation period of strep throat takes 4 days before you can feel the symptoms of strep. Can the strep bacteria be transmitted through oral sex from mouth to penis? Can it be spread by normal sex, vagina to penis? Can it be contracted from swallowing sperm/semen/cum? We have been exclusively intimate for 3 years, there is no chance of std, I also have just recently been tested and unsurprisingly my results were clean, so we are confident that these tiny white blister/bumps must have been caused by strep. However we are looking if anyone else has more knowledge on the strepcock strepdick perdickament.
