Picture - not me - but represents my condition (NSFW) - link to pictures (if reddit fails to load): https://patient.info/forums/discuss/damaged-glans-skin-pics-included-727862?order=latest#topic-replies

I have tried antifungal cream for 2+ weeks and different moisturizing creams for a year. What is this condition? It is painful and does not look good - STDs are ruled out. Also, picture does not do the condition justice, looks a bit worse in 'real life'.

Help is appreciated!! :)
