I'd be inclined to say its anxiety and not an std. If you can't let go of the thought that its an std, you need to get help for the anxiety.
If you get this anxious every time you have sex, perhaps you shouldn't have sex with people who's test results you've not seen on paper.

Nothing to worry about you sound totally focused on your genitals and would have notivced a herpes outbreak by five months the window period is similar to HIV so 90 days after you were clear in all likelihood. It is easy enough to find out if you cannot let it rest......go get a blood test usually can be found for free at a public health clinic in your city. The only thing I would caution is you might already have HSV1 over 50% of the population does and it is asymptomatic oftentimes meaning there are no symptoms. Once you know where you stand you can take appropriate precautions. Herpes not a huge medical problem a minor inconvenience for some and for many nothing to even think about. Good luck all the best.
Please see a Dr, it could be a hundred things. But you have asked this question a couple of times now and you are still worried about it. So that is why i said see a Dr.
could it be some kind of fungal or yeast infection? For some reason my penis only seems to become irritated when think about it.
You have asked this already and I have answered you. What else are you looking for? Tiny cracks has nothing to do with an STD. If you have more questions maybe you should go see a Dr.
