About your question, regarding HIV, oral sex is not considered a risky activity, there are no reports of people getting HIV by doing what you did. There is no need to worry or get tested for HIV, however unprotected oral sex might carry a small risk for other STDs, you could ask in the STD Forum if you wish.
