Factual question about gonorrhea/chlamydia

Hey,
I have a quick factual question about these tow STD's that (hopefully) someone can answer for me. I have not had sexual intercorse in about 6 months and have not been with annyone (at all) in about 4. Recently I have noticed that the opening to my penis has become sore and raw. I do not have pain when urinating, but i may have a very slight clear thin discharge from my penis after urinating. But, I do not have any burning or severe pain when urinating. Question is could this be either gonorrhea or chlamydia, or should i be looking more into urinary tract infections? Also, should this 4-6 month period before i experienced any of these problems eliminate those possibilities (seems like with those, symptoms should show in a couple weeks). Can anyone suggest what my problem might be!?

PS. I recently began using an anti-fungal creame on my inner thighs to treat a small case of jock itch. This is the first time i have used any such creame. Could that be what is irritating my penis opening?
