Penis is dry and flaky and red and itchy at times. M19

Not sure why it started it can't be an STD I haven't had sex before and it kind of just randomly started. Is there anything I can do to help it? M19 5'10 190 pounds. Thank you. Will link the images (nsfw obviously): https://ibb.co/7dbvrgCw https://ibb.co/q39Bsngn
