For about two years now my anus has been raw, and during anykind of physical activity secreting. I have to go to the bathroom multiple times while at work and attempt to wipe it away. The color varies so I can't be sure if it's just fat being secreted as it's sometimes yellow, on bad days a little bit of blood, and sometimes it looks as if I never wiped. I do not have pain during bowel movements, but I at times when the secretion seems to be a bit more heavy there and in general there is more of a paper cut stinging feeling, or a constant burning feeling. I'm a gay male but have not been a receiver or giver of any anal intercourse in over four years. I have been tested for chlymidia since then and was negative. I'm not really sure what to do but have been looking into drastically changing my diet in hopes I will find a trigger. I don't know why this would be a sudden issue that I've never experienced before.
