There is no risk from your protected genital sex. Condoms work.
As for receipt of oral sex, oral sex is an inefficient way to transmit STDs. Of the bacterial STDs only gonorrhea and nongonococcal urethritis (NGU) are transmitted through oral sex; chlamydia is not and without an obvious sore or lesion on your partner’s mouth, the chances of syphilis and herpes is likewise tiny. If you had gotten gonorrhea or NGU you would have most likely developed symptoms of urethritis (penile infection) by now although symptoms onset can sometimes take a week or so. Even if your partner had an STD (any STD and it is likely she did not), most exposures do not lead to infection. In your case, your exposure was brief; I would urge you not to worry. If you wish to be tested, testing at this time for gonorrhea and NGU would be accurate; you could go to your local STD clinic or health care provider to be tested at this time.
STD related infertility is very, very rare and when it occurs is due to treatable STDs. This really is not a concern in your situation.
