"I got a bit of the Seborrheic one year later after sleeping with the woman having 'protected' sex. I do have oily skin and my sister does have a bit of the same thing around her nose but mine is a tad worse."
sounds like in this post you slept with your sister. Now That I got a laugh out of the way! You shouldn't have had a risk from a protected incident, unless the condom broke. If you are concerned you can get tested. Protected sex without failure is no risk.
AIDS does not have symptoms. AIDS is the definition of someone that is HIV positive with a CD4 count of less than 200. HIV may or may not have symptoms. You were not at risk for HIV, you had protected sex.
