Hello,
Thank you for your post.
This situation as described, even under the theoretical circumstances mentioned, would have not put you at any risk of HIV or any other STD. It is completely safe. Therefore there is no need for you to worry, and no need for you to get tested.
Best wishes,
Dr José
I forgot one more thing.. Before handjob she also rubbed by buttocks by pouring oil on to it & rubbing some of which may have gone onto my anus as well. Is that any risk if the oil is contaminated.. Sorry I could not write my thoughts in one go as I am worried. Hope you will understand...
