Welcome to HCM.
The chances of getting HIV infection through oral sex
is very very low.
The tiny dots over the inner aspect of your cheek may not be an injury
or a sore or any STD
. It may be due to associated manifestation of some other dermatological problem or a leukoplakia
. As they are painless herpetic sores also not likely. If you meet your dermatologist
, he/she will help you to treat the same.
The risk of getting HIV is remote and it is better to have a blood check up for HIV with P24 Antigen test or a combo test or with a HIV DNA PCR test 3 weeks after your oral contact and rule out totally from your mind.
Good luck to you.
