Latex condoms don't suffer a minor tear, when they go, they go.
The research shows condoms are safe... period. google condom efficacy studies and you will find that information.
The research also shows oral is "safe." Although the CDC has yet to say this. But all I can tell you is that you can find numerous research regarding this topic and you will see that oral transmission is something that has not been proven to occur. (although there are accountis of it occuring) no research has shown it (yet)
So good luck from this point.
