Hi, I ve read that calamine lotion can be used to treat simple penile contact dermatitis. Is this accurate? To be frank, my condition is caused by masturbation with baby oil (my wife and I haven t had sex in years, due to health problems, and I ve never cheated on her, so it s not an STD). I ve also noticed that antihistamines help. The shaft of my phallus has never been the same since a yeast infection caused by powerful antibiotics to treat pneumonia in 2012. I now seem prone to contact dermatitis there. Your advice is much appreciated. THANK YOU!
