Hello - thanks for asking your question.
To answer your questions:
1) It would be very rare for oral herpes to spread to the genitals. Spread is usually to adjacent areas. If you have herpes lesions in 2 different places, it is likely because of 2 primary infections.
2) It is possible for herpes to last past 2 months. There are cases where the primary herpes infection lasts 5-10 weeks. The longer the lesion stays, the greater chance for recurrence.
3) Without seeing the lesions, I cannot be sure what it is. Balanitis is caused by a fungus (Candida). If not properly treated, it is possible that the inflammation caused by the fungus can manifest as burning.
4) It is possible to have either herpes and fungal prostatitis - although they are uncommon. The treatment would be the appropriate antiviral (if herpes) or antifungal (if fungus) medication. Diagnosis should be performed with appropriate antiviral and antifungal tests on the urine and prostatic fluid.
5) Your PSA absolutely could be elevated because of prostatitis. The PSA should be rechecked after appropriate treatment.
Followup with your personal physician is essential.
