Frequent dermatitis, is a Hiv sign? Me.

I have had a sexual exposure over may 2024, It was an online date and exposure includes rupture condom. I am having a frequent Seborrhoeic dermatitis from last few months and prurigo nodularis over 6 years. This in result got me know, that I have high ige values around 3000, There are frequent change over in the skin. Sudden bumps, frequent follicuilities, eczema over the face and greasy scalp and dandruff. All these symptoms and scenarios makes me think that the reason may be an std. Here I am in search of a suggestion from u doctors to help me with my state. I have taken std testings including. Mostly all.. As Hiv 1&2 antibody, rna pcr, ag/ab, hbsag, anti hcv, vdrl, hsv1&2 antibody, hsv 1&2 urine DNA pcr, hpv urine DNA pcr. Post the exposure I was paranoid with stds and consultation and testings. All the results were negative. As I heard some rare cases might take a larger time for getting positive.. I am wondering how my condition could turn up now. Kindly help me.
