I was just diagnosed with strep throat. i gave my partner oral sex this past weekend. will he get infected on his penis?

Deep throating: As a "Watergate source", I can say that your partner may get a skin infection on the penis if the skin is broken, or mild urethritis (irritation inside the penis). If you inform him (not a reporter) of your concerns and if this develops, he may need to see his MD for Rx (so he won't have to resign.) The bacteria in the mouth are more pathogenic (disease producing) then even the vagina.
