I am sorry that you are so worried about HIV. The activities that you have described are not how we see HIV being passed so it is not likely the symptoms you are experiencing are related to HIV.
It is a good idea to see a health care provider to figure out what could be causing your rash. There are some STIs, like Syphilis, that can cause rashes and can be passed through oral sex but it is only through testing that you will know if your rash is caused by one of these.
