Hi
It is difficult to diagnose conditions online as I would need to see it, take a medical and sexual history and do some tests. What I can do is give you some general suggestions on what it could be and what you can do next.
It’s great that you have been using condoms as that will lower the chance of something passing to you.
It’s common to have itchy skin on the genitals from time to time. Most of the time this can be caused by non-STI things like dry skin, sensitivity to a certain product that was put on the genitals, rubbing of underwear etc…
An STI like pubic lice could also cause the genitals to itch as well.
As you are concerned that it could be an STI I would recommend going to see a health professional for an exam and STI test. You could visit your family doctor or a local walk in clinic for this. You can also have a look at our clinic finder for a clinic in your area.
It is also common that many STI do not show symptoms. Given this we recommend that people go for STI testing. How often you get STI testing really depends on your personal situation. Have a look at our page on when to test.
