Why did my penis turn red after sex?

Q: I am a 29 years old male. A few days back, I had protected sex with my wife. After it, my penis turned red and scratchy and the skin is also peeling off. What can it be due to?

A:Redness of the affected part suggests an inflammatory process. Itching can occur in a number of situations. Two common situations (on penis) where there can be redness and itching are allergic reactions and candidal infection. Both are treatable. Consult a Dermatologist in your area.
