Apologies. Very busy recently.

OK so you got itching on the glans penis after a low risk encounter.

First of all, itching on the glans penis is not a typical symptom of any STD. So unless your symptomology changes, you really can rest assured that this is not a symptom of an STD. That is not to say you did not catch an STD.

If it becomes painful that is a problem and you should see a doctor.

More likely that not, this is a fungal infection or a skin reaction. You can try an OTC cream containing both an anti-fungal and a mild steroid. If it works, it should work within 3 days.

If it does not, see a doctor.
