The corona of my penis (or just below it) frequently gets chafed. I think it is often caused by too much rubbing with two hands and soap and water or shaving cream. The latter is better. I note that seldom does it occur when I masturbate up and down or when I have sex. Actually, I find that having sex with my wife can sometimes bring healing to my penis. I suppose suggesting to her that pussy juice brings healing may not be an appropriate approach to get her to have sex more often!! Anyway, I wonder if any of you have some kind of ointment or oil that you use on your dick to make the skin stay healthier.
