Genital Rash? - genital rash

I am 15 years old with a rash in my genital area. It is very soft, light red with white shirts and almost all of the air, as the pores are swollen, but I'm not sure it's him. I was very scared that this could be an STD, even if they have never had sexual contact with another person, but I do not believe all this. The only detail is that it feels generally very funky. Can anyone help?
