Is this a cause for concern?

This is going to sound really weird but I'm so concerned. I gave my boyfriend of 2 years oral. He's only ever had one other girlfriend and he's never had sex without a condom. After I gave him oral I mouthwashed. I then went home and I later that day kissed my little brother on the lips. Days later he has like a cold sore or something in his mouth. Could this be an STD? I did not have any sore in my mouth when I kissed him. Many thanks

Hello Anonymous,

Welcome to EmpowHER. Thank you for coming to us with your concern that you might have transmitted a STD to your little brother.

Cold sores — also called fever blisters — are a common viral infection. They are tiny, fluid-filled blisters on and around your lips. These blisters are often grouped together in patches. After the blisters break, a crust forms over the resulting sore. Cold sores usually heal in two to four weeks without leaving a scar.

Cold sores spread from person to person by close contact, such as kissing. They're caused by a herpes simplex virus (HSV-1) closely related to the one that causes genital herpes (HSV-2). Both of these viruses can affect your mouth or genitals and can be spread by oral sex. Cold sores are contagious even if you don't see the sores.

Anonymous, the time factor of oral sex to kissing your brother was too short or too soon for you to contact genital herpes (HSV-2) (that is even if your boyfriend were infected) and pass it on to your brother.

Thank you for this! It has helped to ease my mind. I also kissed my brother a day after I gave oral to my bf. And then a day after that my brother got the cold soar or whatever it is. Does this make any difference?

Hi Anonymous,

No, it was too early for the virus incubate and infect you, and then for you to pass it on. We are speculating that your boyfriend even has genital herpes. If you are concerned, consider being tested.
