The 2nd and 3rd pictures are supposed to be switched. 3 should be 2nd. Also forgot to attach my psoriasis on my leg

So on friday I visited a sexual health clinic to get examined for a small lesion on the underside of my lower penile shaft. Basically she said that it probably isn't herpes but couldn't be 100% sure. No swab or blood test done. I'll go through a bit of timeline of events leading to the examination. So 2 weeks ago on the 6th I had unprotected vaginal sex with a girl, no oral or anything else. The next days I had small red painless bumps over my head and under foreskin which the doctor said was probably a fungal infection. They disappeared within a week, so no concern there really. But on Tuesday night I noticed a small red rash which looked like psoriasis (see pic 1), I do have psoriasis on other areas of my body but never genitals. Now I'll mention that on Tuesday night I was in a hot tub at friends house. I'm thinking that it could possibly be dermatitis or something in relation to a fungal infection. So anyway I proceeded, stupidly, to pick the rash as I thought it was an ingrown hair which lead to it look like the image in pic 2. As you can see there is a black line going though the lesion and I'm unsure whether it is a vain or a hair. So after that it scabbed over which I do not have a pic of but basically looked like your text book scab you'd have on your arm from a cut raised and brown crust type. This is the stage the doctor got to examine it at but I did show her the other pictures so she could have a full run down. So that evening I got a shower and the scab fell away leaving it looking like pic 3, again you can see the black line through it. It healed a bit over night but I showered again yesterday morning and it looked like pic 4. Currently it looks like it has almost healed I do not have pic of it but it's just slightly itchy sometimes. I've also added a picture of a psoriasis patch I have on my leg for comparison. There was never any pain or discomfort until I picked at it using my fingers and tweezers! Dumb I know..... I'm probably over thinking this way too hard but I would appreciate some advice because you know yourself a doctor can miss some things out. Cheers guys.
