Redness on shaft of penis

[Ohio1989]

Hi. I have had a weird red area on the bottom half of the shaft of my penis for about two weeks now. I noticed it after i had gone to a health clinic and taken a drug test. While i was taking the test i had "stage fright" and couldn't urinate the first two times i had tried, and stood there for a while with my penis out resting on my jeans at times. i also masturbate daily without lubrication. could this redness be due to trauma from my penis resting on my jeans? or broken capillaries inside of the penis? if i stretch out the skin of my penis the redness disappears. I'm just nervous about STDs, as any guy is. The redness is not painful, is not raised, no fluid is coming from them,and does not itch.  and it's in sort of a "half-oval" shape when penis is soft and erect. I have tried to refrain from masturbating after i had noticed it but i still have  acouple times, and have noticed the redness had gotten worse after masturbation. the only thing i have applied is neosporin, but it hasn't really gone away. also i've cleaned my penis a lot more than normal.  can anybody help me out and tell me what could be going on and what i could do? thanks

Hello,
From the symptoms it can be due to chafing skin or friction rub causing such redness. Wash the areas several times with fresh water. Do not use any cosmetic products at the sites. You can apply some calamine lotion at the rash as it will help in soothing the skin. Also wear cotton undergarments. Application of mild corticosteroid cream and oral antiinflammatories like ibuprofen/acetaminophen are also helpful. If the symptoms are severe then it will be best to consult a dermatologist.

It is very difficult to precisely confirm a diagnosis without examination and investigations and the answer is based on the medical information provided. For exact diagnosis, you are requested to consult your doctor. I sincerely hope that helps. Take care and please do keep me posted on how you are doing.
