it does not itch or hurt or anything but its been there a week now and i have been washing with water and nothing else and dont understand why it is there

If it is balanitis or phimosis before you see a doctor go to the druggist and ask for his recommendation for an over the counter anti fungal cream and then use it as directed
looks normal 2 me ?
Yea, it does look normal but that is because the flash fades out the red rash.
You need to post a photo clearly showing the rash - try taking photos in strong daylight …
