Rashes and cuts on my penis ? I have an itching on my groin due to which I applied a prickly heat powder for relief. So could the problem be due to the powder or what ?

Well you put the powder on to dispel the itching, so how could be the powder causing it? Do you have a lot of hair on your groin area, and does it itch there as well? You may have a parasite problem like crabs. Have been using someone else's towels lately, slept in a different bed?

I don't know about the powder. Ya I have hair near ma groin area which I now have trimmed it off. No, I use my own towel, and sleep in my own bed
