You are not at risk for anything. Doctors on this site have said repeatedly that oral sex with a condom is virtually no risk for anything. They have also said many times that masturbation, even if a little of the partner's vaginal fluids were on your hand, would not be a risk at all. They would advise you to forget about it. They would not advise you to go get testing.
Don't let feelings of guilt or whatever make you think that you have an STD. You don't. You have zero risk. Your chances of getting hit by a meteorite while you are reading this are higher.
The doctors would also tell you, however, that any sexually active people outside of monogamous relationships should go get tested once a year. They would also say this not because of this current encounter, but just because it's what people should do.
I repeat: you aren't at risk. Move on.
