Suggest Treatment For Itching And Scaly Skin On The Testicles

Hi my name I Ryan I'm 6 foot 1 inch, and I'm 23 years old and I weigh 150. I just went to the doctor on Tuesday (last Tuesday) because my testicles were itchy, and the skin is scaly and kinda dark/red. The doctor said it looked like a fungal infection and he prescribed to me clotrimazole which I have been using twice a day.I am to use it twice a day for 2 weeks. The clotrimazole has helped with the itch tremendously and I'm not itching or experiencing discomfort but the skin on my testicles is still dark and scaly and before i went to the doctor and got my prescription I had tried a lot of things to get rid of the fungal infection such as using bleach on my testicles that wasn't diluted in water, stupid I know, I also would put garlic, tea tree oil and vinegar on the oil. So I think that using these products (specifically the bleach) b4 I went to the doctor damaged my skin. I think that the main problem of the skin being damages is the bleach. Ive never had sexual intercourse, but yeah the skin is kinda dark/red, and the skin is scaly (it's like little white bumps on the skin) if the skin doesnt look better when I'm done with my prescription I was planning on going back to the doctor. Please help, thank you
