hello all. i'm in need of some help and i'm a bit worried about this. ok, i've been suffering from an itchy butt crack/anus area for some time now. usually if i put something down there, like lanacaine or gold bond anti itch, it will usually calm down. so i got the urge to itch last night and i was able to get in front of a mirror and look at my butt crack. what i saw stunned me!! my anus looks normal but the skin above my anus and below the top of my butt crack is cracked and a white color!! what can i do? i don't think its an STD(i've get checked once a year, regardless). i've been reading some stuff about yeast infection of the butt crack for men. if so, what does that look like? can can i try to get rid of it? can you use like an anti fungal cream on it, like the stuff for atheletes foot? thanks for helping me out. i appreciate it!!
