This was a no risk exposure as was already indicated on the HIV Prevention Forum. As Dr. Handsfield told you on a prior post, there is no risk to masturbation. In addition, condom-protected sex is safe sex and virtually no risk either. That you masturbated with a potentially vaginal fluid contaminated hand or that her tongue may have touched the tip of your penis does not change that.
It is normal for genital secretions form one's partner to get on each other during mutual masturbation yet no one has ever gotten HIV in this way.. You do not need to worry.
Finally, the problem with using the same condom for both oral and vaginal intercourse is that this may increase the risk for condom breakage. This did not happen to you (when condoms break, they break wide open and it is obvious) so you are OK. In the future however, I suggest you use a different condom for each sex act.
You are fine and do not need testing. No need for worry. EWH
