In general, oral sex is low risk. Your description suggests the possibility of molluscum contagiosum, a minor infection of no important health impact. There are no data about transmission from oral sex, although it probably can occur. If the bumps develop dimples in the center, MC is more likely.
This is speculation, and it is possible the bumps--whether due to MC or something else--are entirely unrelated to the sexual exposure you describe. You should visit a health care provider for definitive diagnosis. Your local health department STD clinic would be an excellent choice, especially if you don't have a regular health care provider.
Good luck-- HHH, MD
i should also add there is not itching or burning or anything like that associated with them, they are simply there...
