The pictures do not look like an STD. In fact, they do not look like an abnormality at all. Many scrotums look velvety as in your photos, an cysts like the one you show are quite normal. I suspect that your feelings of anxiety and guilt have caused you to look at an area you wouldn't normally pay attention to. I urge you to confirm this with a dermatologist as soon as you can, so you can get on with your life.
Take care.

Hey man, I feel your pain. I was just about to post a thread concerning the same thing. My situation is much like yours, except mine has been for a month. I split with my partner of 10 yrs. and I had unprotected sex as well and within about 48 hours, my scrotum turned almost fire red just as yours has. I have no rash at all just extreme burning feeling almost never goes away and intensifies if I start to sweat any or after a shower. I have had some burning on the folds of my skin at my upper thighs and the folds around my butt, without rash as well, but that comes and goes. I thought it maybe jock itch and used Lotrimin to no avail. After about 4 days of this I panicked and thought I had a STD and immediately took 1g of azythromicin to kill any Chylamdia or Gonno. That only seemed to make it worse 2 days later. I then went to the DR and he prescibed Diflucan 150mg to be taken along with Nizoral 2% cream as he thought I had a yeast infection from the antibiotic. That helped intitally and then came back. Took another full week of Diflucan and it helped only for about a day or so at the beginning. I am now on Levaquin 500mg for 10 days with Triamcinolone .1% with lotion 2 times a day. My DR is at a loss as well as myself. I am now back with my partner and I afraid to have any sexual contact with her at all. I feel that if I did have an STD it would be cured with the initial azthromicin and now the 10 days of Levaquin.
DR, what could this be and thank you for any info you could give both of us. This has worked on me mentally as well to the point that it has consumed me.
Sorry Dr., I failed to mention, I talked to a pharmacist that recommended I try a regiment of "Nystatin"...and to no avail. I then got tested for yeast... and the results came back negative. The rash still haunts me daily.
