Is it safe to perform oral sex on someone who is taking antibiotics (NOT for an STI)?

I am currently taking antibiotics (Augmentin = 875mg amoxicillin +125mg clavulanic acid) for a sinus infection. Reading the literature, I noticed that it is not recommended for nursing mothers (unless deemed absolutely medically necessary) because of the presence of antibiotics in the milk.
I was wondering about the amount of antibiotic present in semen and whether it could/would have ill effects on a woman performing oral sex or having vaginal sex.
More specific questions are: how much of the antibiotic would be present in semen? Obviously, only small amounts of semen are generally released. Given that taking small quantities (or an incomplete course) of an antibiotic increase the likelihood of resistant strains of bacteria, is there a risk associated with this quantity of antibiotics? In vaginal intercourse, is there a risk of killing off natural bacteria, increasing the chances of a yeast infection? Are there other risks/considerations?
I am not a biologist, but I do have a reasonaby strong general scientific background, so links to the literature would be particularly appreciated. Informed speculation is also welcome.
