Itchy rash on genital region. (Male)

Recently just discovered that I have some sort of rash due to itchiness on my genital area. When I saw it first I kind of just put it off as it just looked like a red mark, but after inspecting it more closely I realised it was too much of an irregular pattern to be a rash, then just today these 2 dots also started itching and it looks like it’s starting to become a rash. Would be much appreciated whether or not someone can tell me what this is and what I need to do next.
