Welcome back to the forum.
Many uncircumcised men occasionally get balanitis, the medical term for inflamation of the head of the penis, and painless red spots and itchiness are the most common symptoms of it. More severe cases can include diffuse redness, white pus-like exudate under the foreskin, abnormal odor and, in really severe cases, erosion or ulcertation. Balanitis can be caused by yeast or bacteria, although many have no known obvious cause -- called "nonspecific" balanitis.
If herpes infects the head of the penis, technically it is herpetic balanitis. But as you seem to already know, herpes lesions are painful; progress rapidly (1-2 days) from red bumps (not just flat red spots) to obvious blisters, when then can erode, leaving open sores (ulcers) that typicall are very painful.
So based on your brief description, I am far more suspicious of garden-variety balantis than I am of herpes. If you want greater certainty, you need to be professionally examined. However, at this stage it would be reasonable to simply retract your foreskin and wash with soap and water 2-3 times daily and see if it clears up in a few days. If it doesn't, or if you develop any of the more severe symptoms I just mentioned, definitely visit a doctor or clinic for further evaluation.
I hope this helps. Best wishes-- HHH, MD
Oh, one more thing. What's with having unprotected sex with a partner you don't know well? Especially coming from someone who has shown a fair level of anxiety about HIV and other STDs, as reflected in 3 other questions on this or the HIV forum in the past 2-3 years. Please get into the condom habit and stick with it!
