Since a week ago i spoted changes on my penis. I was taking a bath and after that i noticed on my penis red zones or dots. It disapeared after two days so i didnt go to doctor. But today it came back after i had sex with gf, we used condom. Now is more red, still no itchy or pain i dont feel anything. Any idea what it could be, im thinking visition a doctor. I never had any issues down there. Here are some pictures: https://imgur.com/a/sfEah
