Problem in scrotum. Any medications?

Hello sir. I am 17 and a male. I just recently used excess shampoo on my genital area. It also gets dry. I don't have any history of allergies . It's the first time that I used shampoo on my genitals. I dont know how to say but I think that I used it as a lubricant for fast masturbation..... ( rubbed it) I am quite shy sir. Really worried and hesitant to tell it to my parents. It has just been 4 days. I am not able to focus on studies. But now I feel like that skin around it has become quite wrinkled and scrotum looks quite saggy. It feels as if my balls have started becoming quite hangy and skin has become loose.I have applied Coconut oil on the affected area. Now I am not able to have much erection and semen also looks watery. Will this condition go on its own? I am quite worried. Please help me. Do I need to take any medications ??
