Help, Rash in the penis and thigh

For the last week ive had irritation in the penis and balls, with a lot of itch in those areas, and now small rash has grown to my inner thigh area (no itch there) i havent had sex so im guessing this could be some sort of infection from something else? shat is this? what can i do for this? i recently shaved and i thought this was just the aftermath of it but now i am not so sure.
