Is this herpes, candida, or worse?

I don't think it's STD because I haven't had sex in 2 months. I noticed it last week after I got into the hot tub of the site I live in, only the rash on the head of my penis is this big, different parts of my body and my groin itch but not all the time, at different times during the day. I did a candida fungus test, when I first woke up in the morning I took water in my mouth and rinsed it and spit it back into the glass, I left the glass for 2 hours and when I turned it over the bottom was completely white. According to what I learned from the internet the test was positive. Candida can cause this in the penis but I wonder if there is another condition. (The sore on my penis doesn't itch and doesn't hurt when touched) but other parts of my penis itch too.
